Question

the atomic number of an element X is 16 . answer the following. write the number of valence electrons and the valency of element's x​

Answer 1

Answer:

The valency of the element x is '2'.

Explanation:

Atomic number of the element is 16

So first shell can get only two electrons (duplet configuration )

Other shells can have 8 electrons (octet configuration)

so,

electronic configuration of x = 2,8,6

                                               = 2 + 8 + 6 = 16 electrons

It should gain 2 electron to be stable and attain octet configuration.

so ,

The valency of the element x is '2'.
