to become stable, it will gain an electron from a metallic atom
otherwise it will mutually share electron(s) with another non - metallic atom, or even with itself
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 share, gain, or lose electrons in order to achieve a stable configuration, usually a full valence shell. This is known as the octet rule. By doing so, atoms can attain lower energy levels and become more stable.
Choices: a) eject, retain B) lose, gain c) retain,gain d) gain, lose e) lose, retain
Compounds will gain or lose electrons in order to reach a more stable state, ideally a full valence shell.
Far too many - it needs to gain 16 to get to Krypton which is the next noble gas (energetically impossible) - It is far easier for it to lose 2 (which it does) to get to the Argon structure
To become more stable, fluorine is most likely to gain 1 electron and form F- ion.
They become slightly more stable with each decay until they become stable and stop decaying.
They lose it
To become more stable, calcium is likely to lose two electrons to achieve a full outer shell of electrons, forming a positive 2+ ion.
Atoms can gain or lose electrons to become charged particles called ions. When atoms gain electrons, they become negatively charged ions, while atoms that lose electrons become positively charged ions. This transfer of electrons allows atoms to achieve a more stable state by filling their outer electron shell.
Potassium (K), an Alkali Metal in Group 1 with atomic number 19, has a single valence electron in its outermost shell. Therefore it only needs to lose one electron in order for the element to become stable.
