Figure 1 shows one molecule of a compound obtained from crude oil.

A structural formula diagram of a butane molecule. It shows a chain of four carbon atoms (C) in a horizontal line, connected by single covalent bonds. Each carbon atom is also single-bonded to hydrogen atoms (H). There are three hydrogen atoms bonded to the leftmost carbon, two to each of the middle carbons, and three to the rightmost carbon, making a total of 4 carbon atoms and 10 hydrogen atoms.

Give the names of the two elements in this molecule.
