One electron balances the charge on one proton. Their charges are equal and opposite.
If you have one electron for every proton, you have an electrically neutral combination.
an atom with a neutral charge must have the same number of protons as electrons. (think of a proton as having a +1 charge and an electron having a -1 charge. in order for the atom to be neutral, the positive charges must balance with the negative charges) If the atom has 1 proton and 2 electrons, then the overall charge is -1
Approximately 1836
1836 electrons equal the mass of 1 proton. A proton has a mass of 1.0073 amu, a neutron 1.0087 amu, and an electron 5.486 x 10-4. So, it would take 1836 electrons to equal the mass of 1 proton.
Hydrogen has 1 electron, (1 proton) and 0 neutrons.
Hydrogen-1 has 1 proton and 1 electron.Hydrogen-2 (deuterium) has 1 proton, 1 electron and 1 neutron.Hydrogen-3 (tritium) has 1 proton, 1 electron and 2 neutrons.etc. for artificial isotopes

About 1837.This is why you can safely ignore the mass of electrons for any known element in rough calculations; the total mass of the electrons will be well under 0.1 amu.
1 proton,1electron and no neutron

Hydrogen's atomic number is 1. Thus it has one proton per atom. To balance it out electrically then, hydrogen must also have one electron per atom.
1836 electrons equal the mass of 1 proton. A proton has a mass of 1.0073 amu, a neutron 1.0087 amu, and an electron 5.486 x 10-4. So, it would take 1836 electrons to equal the mass of 1 proton.
It depends on what kind of ion:If it's a cation (H+) then there is 1 proton and 0 electrons, so zero.If it's an anion (H-) then there is 1 proton and 2 electrons, so 2 (and that shell is full).
In a neutral atom, the number of protons is equal to the number of electrons. Since each proton has a charge of +1, and electrons have a charge of -1, the positive and negative charges balance each other, and the atom will be neutral.
Hydrogen has 1 electron, (1 proton) and 0 neutrons.
There are 1 proton, 0 neutron and 1 electron in H1.
