Question

write electron dot structure of mg and K atoms

Answer 1

Magnesium is in group two and it has two valence electrons. So, we take those two valence electrons, we put them right next to the element symbol 'mg' for magnesium and that's all there is to it.

The electron dot structure : It is representation of valence electrons around the symbol of atoms. Potassium : As it belongs to s -block , the electronic configuration of potassium is 1s² 2s² 2p⁶ 3s² 3p⁶4s¹ .Since Potassium has 1 electron in its outermost shell , so its electron dot structure involves K with one dot .
