4 pairs
There are four electrons, which is two pair.
Yes it can, if there are no lone, unbonded pairs of electrons around the central atom. Water has 3 atoms, but also has 2 unbonded pairs. It is therefore a bent shape. Carbon dioxide, however, has no unbonded pairs, and is linear with 3 atoms.
None; the oxygen has 2 missing "spaces" for electrons. The two hydrogens have 1 missing "space" for an electron each. Through sharing, all of the atoms fulfill the octet rule. (8 e- in outermost orbital)
Unequal sharing of electrons in a water molecule causes the molecule to be polar.

There are a total of eight. Two pairs are bond pairs and two are lone pairs.

Because Oxygen in water firms two bond pairs of electrons with hydrogen and itself has two lone pair of electrons. Due to the repulsion between different pairs of electrons, those pairs are displaced in 3d space as far as possible with each other. Therefor if results of the bent shape of water molecule.
None. There will be two pairs (for a total of 4 electrons) on the Oxygen atom in the water molecule.

Water
In a water molecule, there are two lone pairs of electrons connected to the oxygen. The lone pairs push the hydrogen atoms, creating a bent shape. In CO2, however, there are two double bonds and no lone electrons on the central atom, hence the molecule has a linear shape.
An unbonded oxygen atom has eight electrons, with six of the electrons located in the valence shell. Two of the valence electrons are unpaired, and therefore can undergo covalent bonding with other oxygen atoms or nonmetals (such as hydrogen).
Oxygen has six (6) valence electrons. In the formation of a water molecule, two (2) of the valence electrons forms a covalent bond with two other hydrogen atoms leaving the water molecule with 2 unshared pairs of electron.
