Answer 2

The Electron dot structures

The electron dot structures  defines the nature of bond and position of atoms of the molecule which are connected in the molecule.

The electron dot structures or Lewis dot formula can be drawn if the molecular formula of the compound is known.

Lewis dot structures also called electron dot structures are diagrams that describe the chemical bonding between atoms in a molecule.

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Here calcium is having an oxidation state of $+2$ called as $\mathrm{Ca}^{2+}$ cation and oxide $O^{2-}$is an anion with oxidation state of $-2$ . Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral $\mathrm{CaO}$.

Electronic configuration of calcium

$\left\right. Ca$: $20$: $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 4 s^{2}$

Calcium atom will lose electron to gain noble gas configuration and form

calcium cation with $+2$ charge.

$\left[\mathrm{Ca}^{2+}\right]$: 18: $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6}$

Electronic configuration of oxygen:

[O]: 8: $1 s^{2} 2 s^{2} 2 p^{4}$

Oxygen atom will gain two electrons to gain noble gas configuration and form oxide ion with $-2$ charge.

$\left[O^{2-}\right]$ : 10: $1 s^{2} 2 s^{2} 2 p^{6}$
