Draw diagrams of the 5 atoms described below. for each atom, use a circle to represent the nucleus, and inside the circle write down how many protons and neutrons the nucleus contains (e. g. 9p, 10n). use concentric circles around the nucleus to represent the energy levels of the atom, and next to each circle write down the number of electrons in that energy level (e. g. 2e): a. atomic number = 1, atomic mass = 1, overall charge = 0 b. atomic number = 7, atomic mass = 15, overall charge = 0 c. atomic number = 11, atomic mass = 23, overall charge = 0 d. atomic number = 11, atomic mass = 23, overall charge = +1 e. atomic number = 17, atomic mass = 35, overall charge = -1
