An ion.
Atoms that gain electrons are called anions, and atoms that loose electrons are called cations
Atoms by definition are neutral. Once they gain or lose electrons and acquire a charge, they are called ions.
Atoms either gain or lose electrons to change their overall neutral charge.
To form a molecule, atoms can share, lose, and gain electrons
Gain of electrons form anions (negative charged atoms).
An atom does not easily lose or gain electrons if is has an equal number of protons and electrons. The charges inside the atom cancel each other, making it neutral.
Atoms that gain electrons are called anions, and atoms that loose electrons are called cations
NO, they are called ions.
Nitrogen gas does not gain or remove electrons. Therefor this gas is neutral.
A molecule is the neutral particle formed when electrons are shared between atoms. The charge is neutral when electrons are shared, negative when they gain electrons, and positive when they lose electrons.
It gains electrons. So if it gains electrons, then the neutral object becomes negatively charged as well.
Atoms by definition are neutral. Once they gain or lose electrons and acquire a charge, they are called ions.
An electron or electrons is/are lost or gained to produce an ion. An atom with the same number of electrons as protons is a neutral atom. If the proton count and electron count do not match, that atom is electrically "imbalanced" and is an ion.
Ions
Ionization
The ion given is formed when the neutral arsenic atom gains three electrons.
The atom is neutral; the cations of Po are of course positive. Polonium lose electrons.
