1. on same side of the central atom

2. at 90° from each other

3. on either side of the central atom

1. protons

2. neutrons

3. electrons

1. The number of isotopes the two bonding atoms have

2. The number of bonding pairs of electrons in the molecule

3. The number of lone pair of electrons in the molecule

4. The abundance of the species of the two atoms

1. a positive

2. a negative

3. no

1. SnCl₂

2. CO₂

3. H₂O

1. there is a lone pair of electrons in one of the atoms

2. one of the atoms in a covalent bond donates a pair of electrons

3. two atoms share one electron each

1. Lone pairs are held at the same distance from the atom they belong to than a bonding pair.

2. Lone pairs are held farther away from the atom they belong to than a bonding pair.

3. Lone pairs are held closer to the atom they belong to than a bonding pair.
