It is a polyatomic, literally meaning many like atoms.
A polyatomic ion is a group of atoms that behaves like a single ion. This group of atoms carries a charge and acts as a single unit in chemical reactions.
Ions. Usually negative ions, but not always.
No, a charge is not indicated on neutral atoms. Neutral atoms have an equal number of protons and electrons, resulting in no overall charge. When an atom gains or loses electrons, it becomes an ion, which carries a positive or negative charge, respectively.
MgBr₂, or magnesium bromide, consists of one magnesium (Mg) atom and two bromine (Br) atoms. In total, there are three atoms in a formula unit of magnesium bromide. The magnesium atom carries a +2 charge, while each bromine atom carries a -1 charge, balancing the overall charge of the compound.
An ion is a particle that carries a charge, either positive or negative, due to losing or gaining electrons. It can be a single atom or a group of atoms that have an overall charge. A molecule is a group of atoms held together by chemical bonds and may or may not carry a charge.
A polyatomic ion is a group of atoms that behaves like a single ion. This group of atoms carries a charge and acts as a single unit in chemical reactions.
a tightly bound group of atoms that behaves as a unit and has a positive or negative charge
An ionized molecule. Common examples are Sulphate ions, Nitrate ions and Phosphate ions.
Protons.
Ions. Usually negative ions, but not always.
Atoms carry a positive charge on the proton and a negative charge on the electron, usually these cancel out.
Electrons.
Any atom that has more electrons than protons carries a positive charge. These atoms are known as negatively charged ions.
No, a charge is not indicated on neutral atoms. Neutral atoms have an equal number of protons and electrons, resulting in no overall charge. When an atom gains or loses electrons, it becomes an ion, which carries a positive or negative charge, respectively.
An atom that carries an electric charge is called an ion, not a neutron. Neutrons are subatomic particles found in the nucleus of atoms that have no charge. Ions are formed when atoms gain or lose electrons, resulting in a net positive or negative charge.

MgBr₂, or magnesium bromide, consists of one magnesium (Mg) atom and two bromine (Br) atoms. In total, there are three atoms in a formula unit of magnesium bromide. The magnesium atom carries a +2 charge, while each bromine atom carries a -1 charge, balancing the overall charge of the compound.
