Oxygen has 6 core electrons.
Since oxygen is not a metal, its ions are not normally written with Roman numbers suffixed, but an oxide ion, with formula O-2, contains 10 electrons.
O₂ refers to a molecule of oxygen, which consists of two oxygen atoms. Each oxygen atom has 8 electrons, so in total, O₂ has 16 electrons. If you are asking about the number of electrons in an ion of oxygen, such as O²⁻ (which has gained two extra electrons), then it would have 10 electrons per atom, totaling 20 electrons for the O²⁻ ion.
An O²⁻ ion, also known as an oxide ion, has gained two additional electrons compared to a neutral oxygen atom. A neutral oxygen atom has 8 electrons, so an O²⁻ ion has a total of 10 electrons. This extra negative charge is what distinguishes it as an ion.
There are two pairs of nonbonding electrons in a carbonate ion, CO32-. Each oxygen atom has two lone pairs of electrons, while the carbon atom does not have any nonbonding electrons in the ion.
If your 3- ion has 8 electrons, you would be an oxygen ion (O^3-). In its neutral state, oxygen has 8 electrons, but as a 3- ion, it has gained an additional 3 electrons, giving you a total of 8 electrons. This means you have a net charge of -3, indicating a strong tendency to gain electrons.
Oxygen has 6 core electrons.
An oxygen ion with a charge of -2 has gained 2 electrons. Oxygen normally has 8 electrons, so with the addition of 2 electrons, the oxygen ion with a charge of -2 will have 10 electrons.
A neutral oxygen atom has 8 electrons. When oxygen becomes an ion, it can gain 2 electrons to become O2-, losing the neutral 8 electrons to become a total of 10 electrons in the ion.
2 core electrons and 8 valence electrons are there in N3- ion.
Since oxygen is not a metal, its ions are not normally written with Roman numbers suffixed, but an oxide ion, with formula O-2, contains 10 electrons.
It needs 2 electrons for this. Oxygen makes -2 ion by gaining 2 electrons. It is the most stable ion that oxygen makes.
O₂ refers to a molecule of oxygen, which consists of two oxygen atoms. Each oxygen atom has 8 electrons, so in total, O₂ has 16 electrons. If you are asking about the number of electrons in an ion of oxygen, such as O²⁻ (which has gained two extra electrons), then it would have 10 electrons per atom, totaling 20 electrons for the O²⁻ ion.

O2- ion has a total of 10 electrons.
Sodium ion (Na+) has 10 valence electrons and oxygen ion (O2-) has 8 valence electrons.
actually there are 6 electrons in carbon and oxygen has 8 electrons and it gains 2 electrons to make it a negative ion so the total number of ions are 32
