Assertion: Valency of sodium is 1.
Reason: An atom of sodium donates 1 electron to atoms of other elements.

a. Both statements are true and statement 2 is the correct explanation of statement 1.
b. Both statements are true but statement 2 is not the correct explanation of statement 1.
c. Statement 1 is true but statement 2 is false.
d. Statement 1 is false but statement 2 is true.

Answer 1

Answer:

b

Explanation:

the solution is correct

Answer 2

Answer:

Option 'a' .

Explanation:

• The electronic configuration of sodium can be written as 2, 8, 1. 2, 8, 1 electrons are distributed in the shells K, L, M respectively.
• Therefore, valence electron in sodium is 1 and it needs to lose 1 electron from the outermost orbit to attain octet.
• Hence, the valency of sodium is 1.

• An atom of sodium (Na) donates one of its electrons to an atom of chlorine (Cl) in a chemical reaction,
• and the resulting positive ion (Na+) and negative ion (Cl−) form a stable ionic compound (sodium chloride;
• common table salt) based on this ionic bond.

I hope this would be the answer you would have expected.
