Answer

(a) [2, 8, 6], as it has three shells — K, L, M.

(b) 16, as atomic number is the total number of electrons so, 2+8+6 = 16

(c) Non-metal, as it has 6 electrons in the valence shell and will accept 2 electrons to complete its octet.

(d) Anion, A2-, as element A has 6 valence electrons so it has a valency of -2 and it will take two electrons, complete its octet and become a negatively charged ion.

(e) Sulphur, as sulphur also has the electronic configuration of [2, 8, 6].

(f) Orbital structure of A and its ion is shown below:
