Question

What is the position of an element in the periodic table if its electron configuration is `1s^2 2s^2 2p^6 3s^2 3p^5`?

Answer 1

VII A group element, 3 period , name of the element is Chlorine

Explanation:

The common electronic configuration of the p block elements is
`nS^2nP^(1-6)`
Here `n=3` and the condition is maintained.
Hence we get that the period of the element of the element is `3` and the group in the long periodic table is 17.
Hope it helps...
