Explain the difference between the electron-pair geometry shape & the molecular structure shape
EPG shows the shape with all types of electron pairs & MS shows the shape with only the bonding pairs of electrons
Explain in detail how a covalent bond is formed.
Covalent bonds are formed when two nonmetals share valence electrons with one another to complete each atoms outer shell.
