Answer to the question asked. The question is, which of these statements is an example of phone settles your first we will discuss the state of what is controlled? We have three rules for the distribution of electrons. First of the first principles. Secondly, the house rules and, thirdly, the principle of excluding forests. So it is a rule, the rule of origin is a rule for the distribution of the distribution of electrons in and different orbitals. And this rule state here becomes rigid if we have available orbitals and electrons available for example, the behavior is and oxygen, oxygen with eight atomic numbers and 16 atomic masks and its electronic configuration is one is two is two and two P two PX and two py too busy. two PZ 1 and here one. They are therefore degenerate orbiters for P P two, P a K two PX two Py N two P Z. Thus, the total number of electrons for the oxygen atom is 224678 and 22467.8. And so we will discuss here in the state of control for the distribution of the electronic sensation of electrons. And so it is said here that the electron will first feel individually with the same spin, and then twice with a positive spin.

So here this weekend, here`s this for one sorbitol and this is for two S-orbitals and it`s for And here we`re going to draw two orbital p one, two and 3 for Dubey. So that`s for a 2-electron city um with opposite spin. And yes, we will feel the electrons and represent them like that. And here, in this orbital, the degenerate orbitals have the same energy. The electrons first feel individually single with the same spin, and then we feel that the electrons remain. The electrons fold twice with positive spin. So here an electron has risen. That`s how it will be here. We explain to him here the road of the houses. So the correct option here is that each orbital in a sublingual is occupied individually before an orbital is doubly occupied. So here is a satisfactory option, a satisfactory home school.

And then, two electrons cannot have the same spin state in the adjacent equivalent orbital. This is therefore false and two electrons cannot have the same sippin state in the same orbital. This is also false and more than two electrons can be in the same orbital as long as they have the same spin space. According to the police, the principle of exclusion here, two electrons will not have the same rotation on the same orbital, so they must have an opposite spin here. And according to a post-principle, electrons are filled from lower energy availability, higher energy is available. So it will feel first, then this and then that. So here the correct option is option a, that each orbital orbital in a subplane is occupied individually. We can say that a field in front of an orbital is doubly and doubly occupied. So this is the right option here If we consider the second rule, the spins of unpaired electrons in single occupied orbitals are equal. The initial spin of the electron in the lower plane decides what the spin of the other electrons would be.

For example, the electronic configuration of a carbon atom would be 1s22s22p2. The same orbital is occupied by the two 2s electrons, although different orbitals are occupied by the two 2p electrons with respect to Hund`s rule. According to the first rule, electrons always enter an empty orbital before pairing. Since electrons are negatively charged particles, they repel each other. When occupying their orbitals, they can easily minimize repulsion. The rule states that for a given electronic configuration, the largest spin multiplicity value has the lowest energy term. It states that if two or more orbitals with the same amount of energy are unoccupied, then the electrons begin to occupy them one by one before filling them in pairs. It is a rule that depends on the observation of atomic spectra, which is useful for predicting the ground state of a molecule or atom with one or more open electron shells. This rule was discovered in 1925 by Friedrich Hund.

Each of these subplanes is divided into orbitals and each orbital can contain a maximum of two electrons. The number of orbitals as follows: According to the first rule, electrons always enter an empty orbital before pairing. The electrons are negatively charged and therefore repel each other. Electrons tend to minimize repulsion by occupying their own orbitals rather than sharing an orbital with another electron. In addition, quantum mechanical calculations have shown that electrons in individually occupied orbitals are less effectively protected or protected from the nucleus. Electronic shielding is explained in more detail in the next section. According to Hund`s rule, the lowest energy term in a given electronic configuration has the highest spin multiplicity value. The electrons enter the sublevel orbitals so that the maximum number of unpaired electrons occupies them. All have identical rotation directions.

This electronic configuration is called maximum multiplicity. The rule was named after German physicist Friedrich Hund, who formulated it around 1927. Hund`s rule has wide application in chemistry, especially in analytical chemistry, spectroscopy and quantum chemistry. Keep in mind that elemental nitrogen typically occurs in nature as molecular nitrogen (ce{N2}), which requires molecular orbitals instead of atomic orbitals, as noted above. Electronic configurations can also predict stability. An atom is more stable (and therefore not reactive) when all its orbitals are full. The most stable configurations are those that have full energy levels. These configurations occur in noble gases.

Noble gases are very stable elements that do not react easily with other elements. Electronic configurations can help predict how certain elements react and which chemical compounds or molecules form different elements. Also consider the electronic configuration of oxygen. Oxygen has 8 electrons. The electronic configuration can be written as 1s22s22p4. To draw the orbital diagram, start with the following observations: The first two electrons pair in the 1s orbital; The next two electrons will pair in the 2S orbital. What remains are 4 electrons that must be placed in the 2p orbitals. According to Hund`s rule, all orbitals will be occupied individually before being doubly occupied. Therefore, two p orbitals receive one electron and one has two electrons.

Hund`s rule also states that all unpaired electrons must have the same spin. By convention, unpaired electrons are drawn as a spin-up, resulting in (Figure 1). An electron does not pair with another electron in a half-filled orbital because it has the ability to fill all its orbitals with similar energy. Many unpaired electrons are present in atoms that are in the ground state. When two electrons come into contact, they exhibit the same behavior as two magnets. The electrons first try to get as far away from each other as possible before they have to mate. For the second rule, unpaired electrons in individually occupied orbitals have the same spins. Technically, the first electron in a subplane could be either “spin-up” or “spin-down”. However, once the spin of the first electron in a subplane is chosen, the spins of all other electrons in that subplane depend on that first spin.

To avoid confusion, scientists typically draw the first electron and all other unpaired electrons in an orbital as a spin-up. Review each of the following instructions. What`s wrong with every statement? How can a return be amended to make it a correct declaration? Stability can also be predicted by electronic configuration. When all the orbitals of an atom are full, it is more stable. The orbitals that have the full energy level are the most stable, for example, noble gases. This type of element does not react with other elements. The Dogs` rule of the maximum multiplicity rule states that for a given electronic configuration, the term with maximum multiplicity is the least energetic. According to this rule, electron pairing in the p-, d and f orbitals can only occur when each orbital of a given subshell contains an electron or is occupied individually. When atoms come into contact with each other, it is the outermost electrons of these atoms, or valence shells, that interact first. An atom is less stable (and therefore the most reactive) when its valence shell is not full. Valence electrons are largely responsible for the chemical behavior of an element. Elements that have the same number of valence electrons often have similar chemical properties.

The design principle states that orbitals with the lowest energy are first filled with electrons. Once the orbitals are filled with lower energy, the electrons move to orbitals with higher energy. The problem with this rule is that it does not provide information about the three 2p orbitals and the order in which they are filled.
