Question

Show the formation of Na2O and MgO 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

Explanation:

Since sodium can lose only one electron of the valence shell and oxygen atom needs two electrons to complete its octet in the valence shell, two atoms of sodium combine with one atom of oxygen. ...
