Question

Answer

Cl attains one positive charge from Na and achieve stability to obey octet rule . .. ...

Answer

It follow the octet law so that Na losses 1 electron in outer most shell and Cl gain 1 electron in outer most shell so they are balanced .

Answer

Explanation:

Stable outer octet of electrons:
A stable outer octet of electrons refers to having 8 electrons in the outermost energy level of an atom. This is achieved when an atom gains, loses, or shares electrons to complete its outermost energy level.

Formation of NaCl:
NaCl is formed when sodium (Na) transfers one electron to chlorine (Cl). Sodium donates one electron to chlorine and both atoms achieve a stable outer octet of electrons.

The loss of an electron:
In the case of chlorine, it has 7 valence electrons in its outermost energy level. To achieve a stable outer octet, chlorine needs to gain one electron. However, in the formation of NaCl, chlorine accepts an electron from sodium, resulting in the loss of one electron from the chlorine atom. This electron transfer allows chlorine to achieve a stable outer octet with 8 electrons.

Explanation of other options:
- The formation of a hybrid orbital: Hybrid orbitals are formed by the mixing of atomic orbitals. Hybridization is not involved in the formation of NaCl, so this option is incorrect.
- The formation of a coordinate bond: A coordinate bond is formed when one atom donates a pair of electrons to another atom. Coordinate bonds are not formed in the formation of NaCl, so this option is incorrect.
- The gain of an electron: While chlorine does gain an electron in the formation of NaCl, it is incorrect to say that this is how a stable outer octet of electrons is achieved in the chlorine atom. The gain of an electron by chlorine is a result of the electron transfer from sodium, not the direct method by which chlorine achieves a stable outer octet.

Therefore, the correct answer is option B, which states that a stable outer octet of electrons is achieved in the chlorine atom during the formation of NaCl by the loss of an electron.
