A ball-and-stick model shows a chain of three black balls, one red ball, and one gray ball. The first (from left to right) black ball has three gray balls attached. The second and the third (from left to right) black balls have two gray balls attached. Spell out the full name of the compound.

the structure of sticks and balls refers to an organic radical, called EThyL.

Explanation:

Ethyl has three main carbons, of which three hydrogen molecules come from the first carbon, two from the second, and three other hydrogen molecules from the third.

The amount of hydrogens to which a carbon can be attached, which according to an organic structure depends on the amount of carbons to which the carbon is attached, a carbon must never exceed 4 bonds.
