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.
The number of electrons is 10.
Oxygen ionizes by gaining two electrons. It becomes a negatively charged ion with the formula O2-.
Potassium ion has 18 electrons.
The H+ ion has no electrons.
Oxygen has 6 core electrons.
The # of Valance electrons in the oxygen famly is 6
2 core electrons and 8 valence electrons are there in N3- ion.
It needs 2 electrons for this. Oxygen makes -2 ion by gaining 2 electrons. It is the most stable ion that oxygen makes.
8
Li+ ion has only 2 electrons in its only shell and they could be considered as both core and valence electrons.
12
O2- ion has a total of 10 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.
2 like oxygen
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
Consider an atom of oxygen in which the nucleus contains 8 protons and 8 neutrons. If it is doubly ionized, what is the charge of the oxygen ion and how many electrons remain in the ion?
