Gaining 2 electrons gives the O atom the stable octet of electrons.
Atoms that tend to gain electrons to achieve a full outer energy level typically form negative ions. These include nonmetals such as fluorine, oxygen, and chlorine. By gaining electrons, they can achieve a stable electron configuration similar to that of a noble gas.
Atoms gain electrons to form negatively charged anions. Atoms lose electrons to form positively charged cations.
Under the usual chemical conditions oxygen gains electrons to form ions. However when ionized by electrical discharges or other high energy physical processes oxygen can lose electrons to form ions.
Arsenic atoms are neutral and they form ions with valency of three.
No, O2 (molecular oxygen) does not have a negative charge; it is a neutral molecule. Each oxygen atom shares electrons in a covalent bond, resulting in a balanced distribution of charge. However, individual oxygen atoms can gain or lose electrons to form charged species called ions, such as O2- (oxide ion), which does have a negative charge.
Negative ions are formed when atoms accept electrons.
Negative ions form when atoms GAIN valence electrons.
Because they want to.
-ide, as in: chlorine -> chloride fluorine -> fluoride oxygen -> oxide etc.
Positive ions
Ionic bond occurs when calcium atoms react with oxygen atoms. Calcium donates two electrons to oxygen to form Ca2+ ions and O2- ions, resulting in an attraction between the oppositely charged ions.

When sodium chloride is dissolved in water, the sodium ions are attracted to the partially negative oxygen atoms of water molecules. These oxygen atoms have a slight negative charge due to their higher electronegativity compared to hydrogen atoms. This attraction results in the formation of a hydration shell around the sodium ions.
Yes, only if there are both ions with positive charges and ions with negative charges among the ionized atoms.
Ions are atoms that have a postive or negative charge because they have loss or gained negative particles (electons).
