How is the cation Ion formed?

Answer 1

A CATION is a positively charged ion . e.g. Na^(+)

The sodium metal has IONISED by losing one electron to form the CATION. (Na^(+)).

Similarly calcium metal ionises by losing two electrons to form the CATION Ca^(2+).

NB An ANION is a NEGATIVELY charged ion e.g. Cl^(-)

Cations and Anions are collectively known as 'Ions'.

So your statement 'Cation ion' is incorrect. You just need the word 'cation'.

Answer 2

A cation is formed when an atom loses electrons to other atoms or groups of atoms. As such, it now has less electrons than protons. Since each electron carry a relative charge of -1 and each proton of +1, there is a net positive charge on the ion equivalent to the number of electrons the atom has lost. Each Na+ has lost one electron and Ca2+ has lost two electrons.

Answer 3

A cation is formed when an atom loses one or more electrons, causing it to have a positive charge. This electron loss occurs typically during chemical reactions where atoms interact with each other to achieve stability through acquiring or losing electrons.
