Argon has 18 electrons and protons...Neutrons is 22
5 protons 8 neutrons try it
Oxygen has: 8 neutrons 8 protons (8 electrons)
A helium atom has 2 protons, 2 neutrons, and 2 electrons.
Calcium typically has 20 protons, but with an added 2 charge, it now has 18 protons due to the loss of 2 positive charges. Calcium-41 has 41 - 18 = 23 neutrons. With a 2+ charge, it will attract 2 electrons, making it have 18 - 2 = 16 electrons.
carbon has : 36000 protons 124000 electrons 348850 calcium
