∙ 8y agoTantalum needs to lose 2 electrons to become stable. Tantalum has 73 protons, so losing 2 electrons will give it a full outer shell of 71 electrons, which is the most stable configuration for the element.
A chlorine atom would gain one electron to become an ion because it tends to achieve a stable electron configuration by having a full outer shell of electrons.
Sulfur gains 2 electrons to become stable, forming the sulfide ion (S2-). This allows sulfur to achieve a full outer electron shell, following the octet rule.
Sulfur can gain 2 electrons to achieve a stable electron configuration, reaching a full octet in its outer shell. The most common oxidation state of sulfur is -2, where it gains 2 electrons to become stable.
Atoms lose or gain electrons to become ions in order to achieve a stable electron configuration, typically through having a full outer shell. Noble gas atoms already have a full outer shell, making them stable and unlikely to gain or lose electrons to become ions. This is known as the octet rule.
5 valence electrons because it needs to gain 3 electrons in order to become stable
Metals will LOSE electrons to become stable.

to gain or lose electrons to become stable
Oxygen has six valence electrons, which means that it needs to gain two to become stable. it takes much more energy for oxygen to lose its 6 valence electrons than it would be to gain 2. When atoms form compounds, they become stable.
Atoms of metals tend to lose electrons to become stable, while atoms of nonmetals tend to gain electrons to become stable. This transfer of electrons creates ions with a full outer electron shell.

Sulfur gains 2 electrons to become stable, forming the sulfide ion (S2-). This allows sulfur to achieve a full outer electron shell, following the octet rule.
Helium is already stable. Hydrogen should gain or lose one electron to be stable.
