Hydrogen with its electron missing is a positive ion and like all ions is very chemically active, trying to become uncharged again.
Lithium(Li) gains 1 electron to become stable.
An electron has a charge of -1. When a Sodium (Na) atom loses one electron, it loses a negative and becomes a stable Sodium ion with a charge of +1.
Helium is already stable. Hydrogen should gain or lose one electron to be stable.
The positively charged subatomic particles that remain when a hydrogen atom loses an electron are protons. Each hydrogen atom normally contains one proton, and when an electron is lost, the proton remains with a net positive charge.
Potassium loses one electron. All Alkali metals lose one electron.
Hydrogen can exist as a positively charged ion (H+) when it loses its electron, or as a neutral atom with no net charge when it has one electron and one proton.
The charge on a hydrogen ion is +1. This means that hydrogen loses its one valence electron to become positively charged.
Cesium loses just one electron to form Cs+
there is one valence electron in hydrogen, and it needs one more electron to become stable
Potassium forms a +1 charge, meaning it typically loses one electron to achieve a stable electron configuration.
The ion charge for sodium is +1. This means that sodium loses one electron to achieve a stable electron configuration.
Sodium loses an electron to achieve a stable electron configuration like the nearest noble gas, which is neon. By losing one electron, sodium attains a full outer shell and becomes more stable with a positive 1 charge.
