Oxygen has six electrons in its outer (valence) shell. According to the octet rule (see related question below), a particle "wants" to have a total of eight electrons in order to be stable. You can also see from the Periodic Table that oxygen has two unpaired electrons, and needs to pair those two. Therefore, oxygen needs to gain two electrons to add to its six. When electrons are added to a particle, there is an overall negative charge due to the imbalance between the positive (protons) and the negative (electrons). Negative ions are called anions.
This means that in most cases oxygen forms a -2 ion (O2-). Diatomic oxygen can also form the ions Superoxide (O2-) and peroxide (O22-).

What ions will the following elements form from phosphorus strontium oxygen gallium lythium?
Phosphorus will form the P3- ion, strontium will form the Sr2+ ion, oxygen will form the O2- ion, gallium will form the Ga3+ ion, and lithium will form the Li+ ion.
Which atom will form an ion sodium or oxygen?
sodium
Can oxygen form a -2 ion?
Yes, oxygen can form a -2 ion by gaining two electrons to achieve a stable octet configuration. This results in the formation of the O^2- ion, known as oxide.
What is the symbol for the oxygen ion?
the symbol for Oxygen is O, the Oxygen ion is 2-. therefore the symbol for the oxygen ion is O2-
What type of ions does aluminum form?
+3 ion
What type of bond will calcium and oxygen form?
Calcium and oxygen will form an ionic bond in the compound calcium oxide. Calcium will donate its two electrons to oxygen, creating a positively charged calcium ion and a negatively charged oxygen ion, which will attract each other to form the bond.
What ions will the following elements form from phosphorus strontium oxygen gallium lythium?
Phosphorus will form the P3- ion, strontium will form the Sr2+ ion, oxygen will form the O2- ion, gallium will form the Ga3+ ion, and lithium will form the Li+ ion.
Does oxygen form ionic bonds?
Yes oxygen can form the oxide ion O2-, and the peroxide ion O22-
What type of charge would an oxygen ion form?
An oxygen ion typically forms a 2- charge by gaining two electrons to achieve a more stable electron configuration.
Which atom will form an ion sodium or oxygen?
sodium
What ion is oxygen most likely to form?
Oxygen is most likely to form the oxide ion (O2-) by gaining two electrons.
Ion of oxygen?
An ion of oxygen with a positive charge is called a "positively charged oxygen ion" or "oxygen cation." This type of ion is less common than the negatively charged oxygen ion (oxygen anion). It forms when an oxygen atom loses one or more electrons.
What ion does a base form in solution?
oxygen
Can oxygen form a -2 ion?
Yes, oxygen can form a -2 ion by gaining two electrons to achieve a stable octet configuration. This results in the formation of the O^2- ion, known as oxide.
What type of bonds are formed when calcium atoms react with oxygen atoms?
Ionic bonds are formed when calcium atoms react with oxygen atoms. Calcium tends to lose two electrons to form a positive ion, while oxygen tends to gain two electrons to form a negative ion. The strong electrostatic attraction between the positive calcium ion and the negative oxygen ion results in the formation of an ionic bond.
What type of ion aluminum form?
+3 ion
Are chlorine and oxygen an ion compound?
No. Chlorine an oxygen will form covalent compounds.
