Recall that carbon is the second most common element in our body and is found in all organic molecules. Recall, too, that carbon atoms contain four electrons in their outer electron shell. With this number of electrons, carbon atoms may form up to four single covalent bonds. Covalent bonds involve the sharing of electrons between bonding atoms. What kind of covalent bond is formed when the electrons are NOT shared equally between the bonding atoms, for example, when hydrogen and oxygen atoms bond in a water molecule?

the correct answer is a

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
