Question

Is $MgO$ a covalent bond?

Answer 1

Hint : In order to answer this question, we need to understand the definition of a covalent and take a look at some of the compounds that use covalent bonds in their bond formation. A covalent connection is created when the electrons from each participating atom are shared equally. Shared pair or bonding pair refers to the pair of electrons involved in this sort of bonding.

Complete Step By Step Answer:
Elements with extremely high ionization energies are unable to transport electrons, whereas those with extremely low electron affinity are unable to absorb electrons. Such elements' atoms tend to share electrons with atoms of other elements or with atoms of the same element in such a way that both atoms attain an octet configuration in their respective valence shells and therefore achieve stability. The term "covalent bond" refers to a link formed by the sharing of electron pairs among distinct or similar kinds of molecules.
The production of additional electrons is not a result of covalent bonding. They are solely linked by the bond. There are extremely strong chemical connections between atoms. Because there are no free electrons in covalently bonded compounds, they do not conduct electricity.
No, magnesium oxide ($MgO$) isn't thought to be bound by covalent bonds. Furthermore, the ionic character of the chemical connection between magnesium and oxygen in magnesium oxide. The significant disparity in electronegativities between magnesium and oxygen causes this.

Note :
The octet rule is used to write electron dot structures of covalent compounds. Except for the hydrogen atom, all of the atoms in the molecule will have eight electrons in their valence shell according to this law. Because only two electrons complete the first shell of hydrogen to achieve the helium configuration, it will have only two electrons.
