Marcus wants to use two objects to compare the sizes of a proton and an electron if he uses a basketball for a proton which object would best represent an electron

If he represents the proton with a basketball, an electron could represent it with a pea or nicke /penny.

Explanation:

A proton has a mass about 1,836 times greater than the mass of the electron.

A proton is less than two trillionths of a millimeter wide, and an electron is approximately m in diameter.
