Why do all bonds form?

• so the number of protons equals the number of electrons

• so an atom can become unstable

• to fill the outermost energy level

Valence electrons are found

• in the innermost energy level of an atom

• in the middle energy levels of an atom

• in the outermost energy levels of an atom

How do covalent bonds form?

• By donating and receiving valence electrons between atoms.

• Scientists still aren't sure.

• Opposite slight charges attract each atom in the compound.

• Sharing valence electrons between atoms
