By losing one or more electrons
what does an atom have in common with an ion?
An ion is a positively or negatively charged atom or molecule.
An ion is an atom with a positive or negative charge.
An atom with a charge is called an ion. If the atom gains electrons, it becomes a negative ion (anion), while if it loses electrons, it becomes a positive ion (cation).
ion
An atom is called an ion if there is a charge on it - positive or negative.
If the number of protons and neutrons are the same, its an atom, if not its an ion
A ion is an electrically charged atom, positive or negative.
atom
Removal of an electron from an atom leaves a positively charged ion.
A one-atom ion is called a monatomic ion. It is formed when an atom gains or loses electrons, resulting in a net positive or negative charge.
Subatomic particles with a positive charge include protons, which are found in the nucleus of an atom. Protons have a relative charge of +1.
