Approx 500 trillion.
The amount of electrons it takes to make 80CU of charge would come as an equation. CU stands for Coulombs. It would take 4.9932078e+20 electrons for 80 CU of charge.
Look up the charge of an electron, then divide 80 microcoulombs by that charge. Note that "micro" means a millionth. Also note that a coulomb is a positive charge, whereas the electron has a negative charge.
Positively charged protons, neutral neutrons and negatively charged electrons
The three basic particles that make up atoms are protons, neutrons, and electrons. Protons carry a positive charge, neutrons have no charge, and electrons carry a negative charge. Together, these particles form the structure of an atom.
When you make an object charged, you have either added or removed electrons from it. Adding electrons makes it negatively charged, and removing electrons makes it positively charged. Electrons move onto the object, giving it a static charge.

Protons have a positive charge, neutrons have no charge (neutral), and electrons have a negative charge. These subatomic particles make up the structure of an atom, with protons and neutrons located in the nucleus, and electrons orbiting around the nucleus.

Electrons (Negative charge), Neutrons (Neutral charge), and Protons (Positive charge)
Protons have positive charge, electrons have negative charge, and neutrons have no charge. The heavier particles, protons and neutrons, make up the atomic nucleus, which always has a positive charge.
electrons
Protons have positive charge, electrons have negative charge, and neutrons have no charge. The heavier particles, protons and neutrons, make up the atomic nucleus, which always has a positive charge.
Positively charged protons, neutral neutrons and negatively charged electrons
You would need 2 more electrons to make a calcium ion neutral, since calcium has 20 protons (+20 charge) and 18 electrons (-18 charge), resulting in an overall +2 charge. Adding 2 more electrons would balance out the charge to become neutral.
An atom that has an equal number of protons and electrons will be neutral and have no charge.
Protons have positive charge, electrons have negative charge, and neutrons have no charge. The heavier particles, protons and neutrons, make up the atomic nucleus, which always has a positive charge.
In one Coulomb of negative charge, there are approximately 6.24 x 10^18 electrons. This is because each electron has a charge of -1.6 x 10^-19 Coulombs, and one Coulomb is equivalent to 6.24 x 10^18 electrons.
