The answer is (2) 2 pairs. The oxygen atoms combine to get stable structure. So after the combination, each atom needs to have 8 electrons. So when they share 4 electrons can satisfy this requirement. Then there are 2 pairs shared.
Answer:
different from the number of their neutrons
Explanation:
They each have one single proton (Z = 1), but differ in the number of their neutrons. Hydrogen has no neutron, deuterium has one, and tritium has two neutrons. ... Their nuclear symbols are therefore 1H, 2H, and 3H. The atoms of these isotopes have one electron to balance the charge of the one proton.

The formula for starch is C6H10O5 which has a ratio of 10 to 5 which reduces to 2 to 1 for the hydrogen to oxygen ratio. The formula for water is H2O which also has the ratio of 2 to 1 for hydrogen. Since the ratios are the same, the answer to the question is "the same". The name used for the category of nutrient that starch falls under should give a strong clue to the chemical formula. It's carbohydrate.</span>
