An ion.
The part of the atom that has a negative charge is the electron. Electrons are located in the electron cloud surrounding the nucleus of an atom and contribute to the atom's overall negative 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.
The name of a cation in an atom is electron. Cation refers to an ion of negative charge. Since electron is also of the same charge, the cation is electron.

The subatomic particle in an atom that has no charge is called a neutron. Neutrons are found in the nucleus of an atom along with protons, which have a positive charge, and electrons, which have a negative charge.
electrons (e-) have a 1- charge, while protons have a 1+ charge and neutrons have a 0 charge.
A negative charge in an atom is neutralized bylosing electrons, so there are the same name protons as there are electronsor having a cation (a positive ion) to form with the negative ion.
Electron is a negative sub atomic particle which revolves round the nucleus.
O2 is the symbolic representation for a diatomic molecule consisting of two oxygen atoms. Each oxygen atom has a general oxidation state of -2. There is generally no special name given to it, other than classifying it as an oxygen atom.
In any atom,there are protons, neutrons and electrons. As the name would suggest, neutrons carry no charge. Protons carry a positive charge and electrons carry a negative charge. So in an atom that has no charge there has to be an equal number of protons and electrons.
negative ion or anionThey are referred to as anions, because they are attracted to the positively charged anode and thus collect around it.
