The forces that hold different atoms or ions together are

Chemical bonds

Explanation:

The chemical bonds hold the different type atoms or ions together.

The type of chemical bonds:

1. Ionic bond;

Ions or atoms changes the electron and form ionic bond. Those atoms gains the electron gets negative charge and those atoms donate the electron gets positive charge.

2. Covalent bond:

In this type of bond atoms share the electrons and form covalent bonds.

3. Metallic bond:

This type of bond are present in the metals. In this atoms are used free electrons to form bonds.

Therefore answer is - -
