What is a covalent bond?
a bond in which electrons are shared by two atoms
a bond in which electrons are transferred from one atom to another
Valence electrons are found
outermost energy level
innermost energy level
some where in the electron cloud

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
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
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
