 23. 

a bond formed when atoms share one or more pairs of electrons.
.
 

 24. 

a covalent bond in which two atoms share one pair of electrons.
.
 

 25. 

a covalent bond in which two atoms share two pairs of electrons.

a nonbonding pair of electrons in the valence shell of an atom; also called lone pair

the energy associated with constructing a crystal lattice relative to the energy of all constituent atoms separated by infinite distances
 

 33. 

a concept of chemical bonding theory that is based on the assumption that atoms tend to have either empty or full valence shells
 

 34. 

a theory that predicts some molecular shapes based on the idea that pairs of valence electrons surrounding an atom repel each other
 

 35. 

in chemistry, any one of two or more possible configurations of the same compound that have identical geometry but different arrangements of electrons
