The total charge would be +17 + (-10) = +7.
The number of electrons are required to predict the charge of the ion.
atomic mass = protons + neutronsprotons = atomic mass - neutrons = 18 - 8 = 10 protons (Neon)In ground state, protons = electrons = no charge-1 charge means gain of 1 e-, so number of electrons = 11 electrons
Electrons have a negative charge. Protons have a positive charge, and neutrons have a neutral charge. Added: Electrons always have a negative charge, value: minus 1.602*10-19 Coulomb.
It should be:# of protons - # of electronsIt gives you the ion charge of the element. For example, Oxygen ion has 8 protons and 10 electrons. Therefore, 8 - 10 = -2 ----> O2-

If you have two electrically neutral objects, and a charge (e.g., an electron) passes from one to the other, then both will be charged. If an electron (with a charge of minus 1 elementary units) passes from object "A" to object "B", and both were neutral initially, then object "A" will have a charge of +1, and charge B, a charge of -1. If this is confusing for you, here is a numerical example.Object A has 10 protons and 10 electrons. The total charge is 10 - 10 = 0.Object B also has 10 protons and 10 electrons, for a total charge of 0.After the electron goes from object A to object B:Object A has 10 protons and 11 electrons. The total charge is 10 - 11 = -1.Object B has 10 protons and 9 electrons. The total charge is 10 - 9 = +1.If you have two electrically neutral objects, and a charge (e.g., an electron) passes from one to the other, then both will be charged.

There is a neutral charge on an atom when the number of protons is equal to the number of electrons. This is most common in the Noble gases, such as Neon (atomic number 10, the second Noble Gas), where there are 10 protons and 10 electrons, with the negative charge on the electrons balancing out the positive charge of the protons exactly.
12 + 10 = 22 charge
12 + 10 = 22 charge
9 protons
Magnesium has 12 protons, so if there are only 10 electrons, then it will have a +2 charge.
The number of electrons are required to predict the charge of the ion.
9 protons
An Oxygen atom has 8 protons and 8 electrons 1 Proton = +1 8 protons = +8 1 electron = -1 8 electrons = -8 Net charge = 0 Oxygen ion has 8 protons and 10 electrons 8 protons = +8 8 electrons = -10 Net charge = -2
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?
An atom has no net charge, and is therefore neutral, as long as the number of protons is the same as the number of electrons. There would be no charge. If there is the same number of protons to electrons, there would be no extra attraction to create a charge.
