How do atoms interact to from molecules?

1. Atoms from molecules to fill vacancies in their outer electron shells

   • An atom will not react with other atoms when its outermost electron shell is completely full. Such an atom is extremely stable and is described as insert.
   • An atom will react with other atoms if its outermost electron shell is only partially full.

2. Chemical bonds hold atoms together in molecule

   • Chemical bonds are attractive forces that hold atoms together in molecule.

3. Atoms gain stability by filling or emptying their outer electron shells. They do this by acquiring, losing, or sharing electrons during chemical reactions.

   • Chemical bonds

4. Types of bonds

   • Ionic
   • Covalent
   • Hydrogen

5. ions

   • Atoms that have lost or gained electrons

6. Covalent bonds forms when atoms fill their outer electron shell by sharing electrons.

7. Polar covalent bonds allow hydrogen bonding, the attraction between the slightly positive hydrogen on one molecule and the slightly negative regions of other polar molecules.
