Question

What is a possible formula of a compound formed when sodium and chlorine bond? nacl4 nacl3 na2cl3 nacl?

Answer 1

Answer: Option (d) is the correct answer.

Step-by-step explanation:

Sodium is an alkali metal and it has atomic number 11. Electronic distribution of sodium is 2, 8, 1.

Whereas chlorine is a non-metal and it has atomic number 17. Electronic distribution of sodium is 2, 8, 7.

Therefore, both sodium and chlorine needs to become stable in nature. Hence, sodium will easily lose its one valence electron and changes into
`Na^(+)` ion. On the other hand, chlorine will readily gain one electron and changes into
`Cl^(-)` ion.

Since, charges on both sodium and chlorine are same. Hence, when both of them chemically combine together then they will result in the formation of sodium chloride (NaCl).

Thus, we can conclude that NaCl is a possible formula of a compound formed when sodium and chlorine bond.

Answer 2

As we know Sodium belongs to Group I metals and it has a tendency too lose one electron and obtain noble gas configuration (Stable Configuration). On the other hand chlorine belongs to Group VII elements (Halogens) and it tends to gain one electron and attain noble gas configuration.
So, sodium attains +1 charge and chlorine attains -1 charge. In order to form a neutral compound, exactly one +ve and one -ve charges are required. Therefore, one sodium and one chlorine ratio is present in NaCl.
