Can someone help me over here? I need an negative charge and also another thing is that in a question it asked me to use something that would represent an ion. I’m not sure on what to choose either Hydrogen or Helium but just please send help. Please just please help me I NEED URGENT HELP :(

Explanation:

From the image given;

Number of Protons = 1

Number of Electrons = 1

Number of Neutrons = 0

Positive Charge (From the protons) = + 1

Negative charge (From the electrons) = -1

Atomic mass = Mass of Proton + Mass of Neutron = 1.00727647 amu + 0.000549 amu = 1.00784 amu

Overall Charge = Positive charge + Neutral charge = 1 -1 = 0 (Neutral atom)
