Question

(6) Show the formation of Na2O and CaCl2 by the transfer of electrons

Answer 1

Answer:

Na2O is, therefore, an ionic or electrovalent compound. Formation of MgO: It has two electrons in its outermost shell. So, the magnesium atom donates its 2 valence electrons and forms a stable magnesium ion, Mg2+ to attain the electronic arrangement of neon gas

Answer 2

configuration of Na - 2,8,1
no. valence electrons ==> 1
configuration of O => 2,6
no.valence electrons ===> 6
