Electron is a negatively (-) charged particle found in a atom. Unlike proton and neutron, electron is found in orbital shells of atom, but not in nucleus. Electron are very small that is why they don't contribute to the Atomic Mass of a element. Electron are responsible for forming ions and take part in chemical reaction.
Gain of an electron transform the atom in an anion.Loss of an electron transform the atom in a cation.
yes
It forms a new atom.
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.
when an electron is added to an atom, the atom will acquire a negative charge.
it forms an ionic bond with the atom it has received an electron from.
The hydrogen atom has 1 electron.
This atom lose an electron.
A valence electron is one that occupies the highest energy level for any electron in a particular neutral atom. (There may be more than one such electron in a single atom.) It is an electron in the outermost shell of the atom.
When you add an electron to an atom, the atom becomes negatively charged and is called an anion. When you subtract an electron from an atom, the atom becomes positively charged and is called a cation.
When an atom loses an electron, it becomes a positively charged ion.
An atom with one extra electron is called an anion, while an atom with one missing electron is called a cation.
