A cation is formed by the loss of an electron from the valence shell of an atom.
Aluminum, sulfur, fluorine, phosphorus, iodine, and neon
Li loses one electrons. Cl gains the electron.
No gain of electron is reduction. An atom that gains electrons is reduced in a chemical reaction. OIL RIG; oxidation is loss, reduction is gain
The alkali metals have a low electronegativity and they easily loss an electron.

A cation is formed by the loss of an electron from the valence shell of an atom.
By the loss or gain of an electron.
With the loss of electron a neutral atom becomes positive ion and loss of electron is known as oxidation.
cation
Because potassium loss easily an electron.
loss of electron in electronegativity ion
A new ionic species - Na- (it does not exist) Perhaps you meant the loss of an electron? In this case, sodium readily loses an electron to form Na+.
An electron has a negative charge. If an atom loses an electron it creates an ion with a positive charge. If an atom gains an electron it creates an ion with a negative charge.
Aluminum, sulfur, fluorine, phosphorus, iodine, and neon
To produce a negative ion (anion): an electron is gained. To produce a positive ion (cation): an electron is loss.
It loses mass.
