Zero. (Ions have charge; atoms are always neutral.)
they are the cations

An ion is an atom (or group of atoms) with an electrical charge.
An atom or group of atoms with a negative charge is called an anion. Anions have gained one or more electrons, leading to an overall negative charge.
It is an ion.
Ion
That's called an ion.
A polyatomic ion is a group of atoms with a charge.
When an atom or group of atoms becomes electrically charged, it is referred to as an ion. If it has a positive charge (+) it is called a cation, and if it has a negative charge (-), it is called an anion.
Yes, an atom can have charge. Atoms consist of protons, which have a positive charge, neutrons, which have no charge, and electrons, which have a negative charge. The overall charge of an atom depends on the balance of these particles.
Atoms are neutral in charge
It's called an ion, and it simply means a charged atom (or group of atoms.)
