A science student compares three neutral atoms designated as D, E, and G. Atom D has an atomic number of 17 and a mass number of 35. Atom E has the same number of neutrons as atom D, but its mass number is 37. If atom G has the same atomic number as atom E and contains 21 neutrons, what are the atomic number of atom E and the mass number of atom G?

A) Atomic number of E is 18; mass number of G is 39

B) Atomic number of E is 19; mass number of G is 40

C) Atomic number of E is 20; mass number of G is 41

D) Atomic number of E is 17; mass number of G is 38
