Agiven atom has 3 protons, 4 neutrons, and 3 electrons. describe how you can use those three values to describe the structure, charge, and mass of the atom.

For structure.- There would be two shells, K & L , and there would be one electron in valence shell.

For charge.- proton-electron = 3-3 = 0. so, there is no charge

Mass.- proton + neutron = 3+4 = 7
