A molecule of nitric oxide has 15 electrons overall, 7 from the nitrogen atom and 8 from oxygen.
A molecule of nitric oxide has 15 electrons overall, 7 from the nitrogen atom and 8 from oxygen.
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.
MgOMagnesium: 2 Valance Electrons (Charge is +2)Oxide: 6 Valance Electrons (Charge is -2)Hint: Oxide has a charge of -2 and so does Oxygen. Check the periodic table for the elements that have a -2 charge (group 16) and you will find oxygen as the first element in that group. Periods define how many energy levels the element has, just so you know. Oh and this is ionic.Hope this helps!
Sodium oxide has the chemical formula of Na2O. To find the number of electrons in this molecule, we first need to know the number of electrons for each of its constituent atoms. The number of electrons in a neutral sodium atom is 11 and the number of electrons in a neutral oxygen atom is 8. So, after doing some simple arithmetic, we find that sodium oxide has 2*11 + 1*8 = 30 electrons per molecule.
Nitrogen oxide, with the chemical formula NO, has a total of 12 valence electrons - 5 from nitrogen and 6 from oxygen, with an additional electron due to the negative charge.

An oxide ion (O^2-) has 0 unpaired electrons. It has a full outer electron shell with 8 electrons, fulfilling the octet rule.
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.
Calcium oxide has 20 electrons from the calcium atom, and 8 electrons from the oxygen atom, totaling 28 electrons.
Depends on what you mean by number of electrons. Calcium has 20 electrons and oxygen has 8 electrons for a total of 28 electrons. But if you mean how many VALENCE electrons, then the calcium has 2 and the O has 6 for a total of 8 valence electrons.

Nitrogen oxide, with the chemical formula NO, has a total of 12 valence electrons - 5 from nitrogen and 6 from oxygen, with an additional electron due to the negative charge.
Sodium oxide has a total of 8 valence electrons (1 from sodium and 6 from oxygen) because sodium is in group 1 and oxygen is in group 6 of the periodic table.
Oxide has a -2 charge because oxygen, which is part of the oxide ion, strongly attracts electrons. Oxygen has 6 valence electrons and needs 2 more electrons to achieve a stable octet configuration, so it gains 2 electrons to form the oxide ion with a -2 charge.
The number of valence electrons in N and O is five and six, respectively. The total number of valence electrons in N2O is 16.
First, calcium oxide is an ionic compound and so does not form molecules. In one formula unit (ionic equivalent of a molecule) of calcium oxide there is 1 oxygen (8 protons) atom and 1 calcium atom (20 protons) for a total of 28.
