one more proton than electron
The ammonium ion has a plus 1 charge because it is formed by the donation of a lone pair of electrons from the nitrogen atom to a proton, resulting in an extra positive charge on the nitrogen atom. This donation creates a more stable structure with a full outer shell of electrons for nitrogen.
Many different chemical species can form an ion with a plus 1 change. The most common example of cations of this type are the alkali metals, such as sodium and potassium.
Proton emission is a type of radioactive decay where an atom emits a proton with a mass number of 0 and a charge of plus 1. An example of a radioisotope that undergoes proton emission is iodine-123.
The charge of electrons in an atom is negative, with a magnitude of -1. This negative charge is equal in magnitude but opposite in sign to the positive charge of protons in the nucleus, which helps maintain the overall neutrality of the atom.
The sodium atom is much bigger than a sodium cation with a plus 1 charge, because the "lost" electron of the ion had a higher principal quantum number than any remaining electron in the ion and therefore was distributed through a larger volume of space than any of the remaining electrons.
HCl is formed.
Helium atom is neutral and has no charge. It becomes a positive ion with a charge of +1 when it loses an electron.
Proton
Electrons. Electrons carry a negative charge so when one is removed from the atom the atom gains a net positive charge.
Because of the number of electrons in the outermost shell of the atom.
