The proton! The number of protons in an atom's nucleus is the "ID card" of that atom. If an atom has 6 protons, it's carbon. If it doesn't have 6 protons, it's not carbon. Simple as that!

Neutrons have neutral charge.
The atom is the smallest part of matter that represents a particular element. For quite a while, the atom was thought to be the smallest part of matter that could exist. But in the latter part of the 19th century and early part of the 20th, scientists discovered that atoms are composed of certain subatomic particles and that, no matter what the element, the same subatomic particles make up the atom. The number of the various subatomic particles is the only thing that varies. Scientists now recognize that there are many subatomic particles (this really makes physicists salivate). But in order to be successful in chemistry, you really only need to be concerned with the three major subatomic particles: Protons Neutrons Electrons

nuclei
Electron is a negative sub atomic particle which revolves round the nucleus.
Now the term negatron is not used; in the past was rarely used to name an electron or an antiproton.
The positively charged particle in an atom is a proton. Proton - positive Neutron - neutral Electron - negative
Not sure if you mean this... A neutral atom becomes an ion by losing or gaining electrons.

Electrons is the subatomic particle that derived its name from the Greek word for a type of semiprecious stone.
