Explanation:

First you have to count protons, neutrons and electrons for each atom.

A: 4p, 5n, 4e

B: 2p, 2n, 1e

C: 8p, 8n, 7e

D: 13p, 14n, 13e

E: 9p, 10n, 9e

F: 7p, 7n, 8e

If an atom has the same number of protons and electrons then it is neutral:

A, D and E are neutrals.

The mass of an atom is related to the number of protons and neutrons, the one with the largest amount has the greatest mass:

D has 27 protons + neutrons.

The atom name is related to the number of protons, you can look a periodic table and take the name of the atom with the same number of protons for each one of the given atoms.

A: Beryllium

B: Helium

C: Oxygen

D: Aluminium

E: Fluorine

F: Nitrogen

it would be a gas formation
