Yes it gains two electrons, because it already has 6 valence electrons..it gains two to make it an even 8 (because of the Octet Rule). Since it gains two electrons it makes it O^-2

∙ 6y agoOxygen cannot gain two electrons when forming an ionic bond.

∙ 6y agoYes. For example, sodium oxide has the formula Na2O, which is an ionic compound formed when two sodium atoms each give up an electron to oxygen, forming two Na2+ ions and one O2- ions.

What is it called when gain of electrons or H?
Gain of electrons form anions (negative charged atoms).
How do positive and negative ions forms?
Atoms gain electrons to form negatively charged anions. Atoms lose electrons to form positively charged cations.
Do oxygen gain or lose electrons?
Oxygen is an oxidizer, it will gain electrons in a reaction to complete it's valence shell.
What group in the periodic table forms anions?
The elements in group-15 , 16 and 17 have 5,6 ad 7 valence electrons respectively , so they gain electrons to form anions.
What kind of element metal or nonmetal can form an anion?
Non-metals gain electrons. Hence, they can easily form anions.
What kind of atoms gain electrons?
Generally non-metals gain electrons and form anions.
What is it called when gain of electrons or H?
Gain of electrons form anions (negative charged atoms).
How do positive and negative ions forms?
Atoms gain electrons to form negatively charged anions. Atoms lose electrons to form positively charged cations.
Do oxygen gain or lose electrons?
Oxygen is an oxidizer, it will gain electrons in a reaction to complete it's valence shell.
Do anions and cations share electrons during ionic bonding?
Yes anions and cations share electrons. Anions gain electrons and cations loose electrons.
What group in the periodic table forms anions?
The elements in group-15 , 16 and 17 have 5,6 ad 7 valence electrons respectively , so they gain electrons to form anions.
What kind of element metal or nonmetal can form an anion?
Non-metals gain electrons. Hence, they can easily form anions.
Which type of elements gain electrons when they form bonds?
It is done by Non-metals and metalloids.They form anions
Do in ionic bonding atoms loose or gain electrons?
Actually both. Atoms gain electrons to form negatively charged anions whereas when atoms lose electrons positively charged cations are formed. Ionic bond is the force of attraction between cations and anions
What is an aion and where can you find it on the periodic table?
Anions are negatively charged atoms.Non metals gain electrons to form anions. They are placed on right side in the periodic table.
How does a cation form?
Cations form when atoms lose electrons, they gain a positive charge as a result.
When metals and non metals react whichs atoms gain electrons?
Nonmetals usually accept electrons to become negative ions (anions), e.g. Cl + e- --> Cl-.
