In the phet simulation, click the green + symbol to expand the net charge tab. drag protons, neutrons, and electrons and notice how this affects the information displayed in the tab. for extra conceptual practice, click on the game menu and test your knowledge on the first difficulty rating. rank the atoms based on charge from most negative to most positive.
rank the following atoms from most negative to most positive charge. to rank items as equivalent, overlap them.

a) 9 protons, 11 neutrons, 10 electrons
b) 4 protons, 4 neutrons, 2 electrons
c) 8 protons, 8 neutrons, 10 electrons
d) 3 protons, 3 neutrons, 3 electrons
e) 1 proton, 0 neutrons, 0 electrons
