Which of the following is an example of an electric force that occurs in atoms?

O

A a proton attracts an electron

B. a proton attracts a neutron

Ca proton attracts another proton

o. a proton repeis an electron

A proton attracts an electron

Explanation:

When an electron attract proton electrostatic forces occur between them.

Consider the example of ionic compound sodium chloride.

Ionic bond:

It is the bond which is formed by the transfer of electron from one atom to the atom of another element.

Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.

For example:

Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion. Both atoms are bonded together electrostatic attraction occur between anion and cations.
