Question

An atom X which has atomic number 16 and mass number 32 . Electron configuration No of electrons in valence shell Metal or non metal

Answer 1

Given an atom 'X' with

(Z) = 16 ; (A) = 32

1. Electronic Configuration = 2,8,6
2. Number of Valence Electron = 6
3. See, Valency of such atom is (-2) I.e it requires 2 e- to complete its octate so it's a Non-Metal
