Question

which of the following fundamental forces is primarily responsible for the formation of chemical bonds between atoms? 1 point
electromagnetic force
weak nuclear force
strong nuclear force
gravitational force
what type of chemical bond involves the electrostatic attraction between oppositely charged ions? 1 point
metallic bond
orbital bond
molecular bond
ionic bond

Explanation:

1. Chemical bonds between atoms are formed mainly due to the electromagnetic force which acts on charged particles like electrons and protons in atoms. The other forces - weak nuclear force is involved in radioactive decay, strong nuclear force holds the nucleus together, and gravitational force is too weak on the atomic - scale to play a role in chemical bonding.
2. An ionic bond is defined as the electrostatic attraction between oppositely - charged ions. Metallic bonds involve a sea of delocalized electrons and metal cations, and orbital and molecular bonds are not defined by the electrostatic attraction between oppositely - charged ions.

Answer:

1. Electromagnetic force
2. Ionic bond
