An ion is an atom with a net electric charge. An ion is formed when an atom either gains or loses a valence electron. Atoms with an unfilled outer shell tend to gain or lose electrons so they can achieve a filled outer shell. Atoms that gain an electron are negative ions, and atoms that lose an electron are positive ions.
Atoms become positive ions when they lose an electron in a reaction. An electron is negative and a proton is positive, so when the atom loses an electron it will have more positive than negative, and the atom will be a positive ion. The atoms at the left of the periodic table usually lose electrons in reactions.
Sodium atom lose an electron.
It becomes unstable, so noble gases will not lose or gain electron
When atoms either lose or gain electrons they are referred to as ions.
They lose valence electron(s), becoming positively charged ions.

No. They gain electrons
1. Gain an electron. 2. Lose an electron.
Neither. It does not form ions.
se
As a neutral atom lose an electron then it becomes a positive ion As it gains an electron then it becomes a negative ion
Group 1 elements a.k.a. Alkali metals lose 1 electron to form 1+ ions
The atoms of the group 1 elements, called the alkali metals, lose one electron and form positively charged ions in order form ionic compounds with negative ions of nonmetals, or negatively charged polyatomic ions.
It shrinks loosing an electron.
Atoms become positive ions when they lose an electron in a reaction. An electron is negative and a proton is positive, so when the atom loses an electron it will have more positive than negative, and the atom will be a positive ion. The atoms at the left of the periodic table usually lose electrons in reactions.
Ions are formed when atoms gain or lose electrons in their outer orbit/shell. Electrons are negatively charged so if they lose an electron they become positively (plus) charged.
