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

The purpose of promoting one or more electrons in the process of forming hybrid orbitals is ___________________
to increase the number of unpaired electrons
to increase the number of orbital
to make orbital have same the shape and energy
to use the empty d-orbitals
