An atom looses or gains electron to become ion. Ions are +ve and -ve atoms.
what does an atom have in common with an ion?
When an atom has an electric charge it is called an ion.
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.
ION A positively (+) charged ion is named a CATION A negatively (-) charged ion is named an ANION NB When an atom becomes a charged species it is no longer an atom, but an ION . An atom has a neutral charge.
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.
