Question

Assertion (A) : Sodium and aluminium show similar properties

Reason (R): Aluminium has three valence electrons.

(i) Both (A) and (R) are true and (R) is the correct explanation of (A).

(ii) Both (A) and (R) are true, but (R) is not the correct explanation of (A),

(iii) (A) is true but (R) is false,

(iv) (A) is false but (R) is true​

Answer 1

Answer:

ii) Both assertion and reason are true, but reason is not the correct explanation of assertion.

Explanation:

Sodium and Aluminum show similar properties because they lie in same period. Both can loose electrons and become electropositive.

Aluminum has three valence electrons and Sodium has 1 valence electron. The no. of electrons in the outermost shell do not symbolise that they show similar properties.

Answer 2

Answer:

false may be I think so hmmmm
