Question

Electrovalent compounds are formed in the following reactions:

1. $2\mathrm{Na}+{\mathrm{Cl}}_2\to 2{\mathrm{Na}}^{+}{\mathrm{Cl}}^{-}$
2. $2\mathrm{Mg}+{\mathrm{O}}_2\to 2{\mathrm{Mg}}^{2+}{\mathrm{O}}^{2-}$

Write the electronic configuration of the ions of the electrovalent products.

Answer 1

Part 1: Electrovalent Compound

1. The compound formed as a result of donating and accepting the electron to complete the noble gas configuration are called electrovalent bonds.
2. A bond between a metal and a non-metal is an ionic bond or electrovalent bond.

Part 2: Electronic configuration of the ions of the electrovalent products

1. $2\mathrm{Na}+{\mathrm{Cl}}_2\to 2{\mathrm{Na}}^{+}{\mathrm{Cl}}^{-}$
   $2{\mathrm{Na}}^{+}{\mathrm{Cl}}^{-}$ : $2\left[\underset{(2,8)}{{Na}^{+}}\underset{(2,8,8)}{{Cl}^{-}}\right]$
2. $2\mathrm{Mg}+{\mathrm{O}}_2\to 2{\mathrm{Mg}}^{2+}{\mathrm{O}}^{2-}$
   $2{\mathrm{Mg}}^{2+}{\mathrm{O}}^{2-}:2\left[\underset{(2,8)}{{Mg}^{2+}}\underset{(2,8)}{O^{2-}}\right]$
