one more proton than electron
there would be a plus (+) charge. Electrons have a negative charge so when a neutral atom loses an electron, it becomes positive. Another word for this is a cation.
19Ne
To form a 1+ ion a lithium atom must lose 1 electron. The same goes for any other atom.
No matter where an electron happens to be -- in an atom, outside of an atom, near an atom -- its charge will ALWAYS be negative one atomic charge.
The charge of an atom who captured a single elektron is - or -1
HCl is formed.

Proton
Electrons. Electrons carry a negative charge so when one is removed from the atom the atom gains a net positive charge.
Helium does not form ion.
Because of the number of electrons in the outermost shell of the atom.

-1
-1 charge
That depends on the number of protons and electrons present. One electron has a charge of minus one. A proton has a charge of plus one. Add charges to arrive at the charge of the atom total. Example: an H+ ion consists of a single proton, and has no electrons. Its charge therefore is +1.
