Question

Which type of bonding involves the complete transfer of a valence electron from a less electronegative atom to a more electronegative one? ionic bonding metallic bonding covalent bonding hydrogen bonding

Answer 1

ionic bond involves complete transfer of electron

Answer 2

Answer: Option (a) is the correct answer.

Explanation:

When an electron is transferred from one element to another then the bond formed is called ionic bond.

Thus, we can conclude that when there is complete transfer of a valence electron from a less electronegative atom to a more electronegative one then it results in the formation of ionic bonding.

The bonding between the metal atoms only is called metallic bonding. Hence, option (b) is not correct.

Whereas when an electron is shared by two elements then the bond formed is called covalent bond. Therefore, option (c) is not correct.

Hydrogen bonding is a dipole-dipole interaction that exists when a hydrogen atom is bonded to an electronegative atom. Therefore, option (d) is not correct.
