What is the force that holds atoms together to form molecules?

Answer 1

The force that holds atoms together to form molecules is called chemical bonding. More specifically, it is the electromagnetic force that holds atoms together through the sharing or transferring of electrons between them. This force can be attributed to the attraction between the positively charged atomic nucleus and the negatively charged electrons. The two main types of chemical bonding are covalent bonding, in which atoms share electrons, and ionic bonding, in which electrons are transferred between atoms.
