8 proton
The number of protons present in an ion is equivalent to its atomic number.
The number of protons is 7.
Magnesium oxide (MgO) consists of magnesium (Mg) and oxygen (O) ions. Magnesium has 12 protons, while oxygen has 8 protons. Therefore, in magnesium oxide, there are a total of 12 protons from magnesium and 8 protons from oxygen, resulting in 20 protons in total.
16 protons and 18 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.
An oxide ion has 8 protons. This is because it is an oxygen atom that has gained 2 electrons to become negatively charged. The number of protons remains the same as the number of protons in a neutral oxygen atom.
The oxygen atom and oxide ion have the same number of protons, which is 8. The oxide ion, however, has gained two electrons, giving it a charge of -2, whereas the oxygen atom is neutral.
how many protons does the carbonate ion have?
The number of protons present in an ion is equivalent to its atomic number.
The neutrons and protons in the nucleus do not change when electrons are removed from an atom. Even when two electrons are removed. Oxygen has several isotopes, with 8 protons and either 8, 9, or 10 neutrons... all representing stable isotopes. 8 neutrons is most common on Earth.
7 protons
Eight protons in this ion.
Nitrous oxide is N2O and has 22 protons (7 from each nitrogen, 8 from oxygen)
The number of protons is 7.
No neutral element has these characteristics. However, the oxide ion, O-2, does have them.
CO3 Carbon - 6 protons Oxygen - 8 protons 6 + (8*3) = 30 protons. Therefore carbonate ion has 30 protons.
The answer is 81 protons.
