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.
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.
Oxygen can ionize by losing electrons to form a positively charged ion. This can occur when an oxygen atom gains enough energy to overcome the attraction of its electrons, causing one or more electrons to be ejected from the atom. The resulting oxygen ion will have a positive charge due to the loss of negatively charged electrons.
The number of electrons is 10.
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.
The oxygen atom would have a charge of -2 after gaining two electrons to become an oxygen ion.
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
