Question

An element has atomic number 16 fullstop its valency is -2 . Is this statement true or false

Answer 1

Answer:

The answer is true.

Reason:

Atomic number given is 16.

So, it's electronic configuration is 2,8,6.

To attain stability, it gains 2 elections.

Therefore, it's valency is -2.

Answer 2

Answer:

True.

Explanation:

If an element's atomic number is 16, then it's electronic configuration will be 2(K), 8(L), 6(M).

Therefore, it will require 2 electrons in it's valence shell, i.e., (M) shell.

So, the statement is true as it's valency will be -2 for the above reason.
