Question

What is the difference between lone pair and a negative charge

Answer 1

A  lone pair is a pair of valence electrons that are not shared with other atoms. They are also known as non-bonding electrons.

If an ion has more number of electrons than the number of protons, then it is a cation and has a negative charge. This anion can use the negative charge to bond with cations.

Hope it helps you buddy

Answer 2

Answer:

Lone pair are pairs are electron pairs which do not participate in reaction.

Like oxygen has 2 lone pairs

F,Cl - 3 lone pairs

whereas:

Negative charge is acquired due to the addition of electron to a neutral atom.

O + 1e⇆ O-
