Step-by-step 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)
