2 unbalanced electrons have a 2- charge on the molecule/atom
(a) a sodium atom with 11 protons, 11 electrons, and 12 neutrons (b) a calcium atom with 20 protons, 18 electrons, and 20 neutrons (c) a helium atom with 2 protons, 2 electrons, and 2 neutrons (d) an iron atom with 26 protons, 26 electrons, and 30 neutrons
The net charge of the particle would be +1, since protons have a charge of +1 and electrons have a charge of -1. Subtracting the total negative charge from the total positive charge gives a net positive charge of +1.
its charge is 0. Protons have a positive charge, while electrons have a negative charge (neutrons have no charge at all). So ten protons will balance out ten electrons, making the net charge 0.
Electron's have a negative charge, Protons have a positive charge.
Electrons possess a negative charge.
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.
The charge on a magnesium ion with 10 electrons (Mg2+) is +2.
An element you have a +2 charge It is had lost electrons. It would have to lose the same number of electrons that its positive charge is. So it would have lost 2 electrons.
-2 neutrons = 0 = no charge electrons = -1 = negative charge positrons = +1 = positive charge
The charge of nickel when two electrons are lost is +2. When nickel loses two electrons, it becomes a cation with a charge of +2.
Magnesium has 12 protons, so if there are only 10 electrons, then it will have a +2 charge.
Beryllium is element 4, so the "neutral" atom would have 4 protons and 4 electrons. In order to have a "-2" charge, it would need 6 electrons.
There are 2 electrons in an oxygen ion with a charge of -2. This is because oxygen normally has 6 electrons, but when it gains 2 extra electrons to become an ion with a charge of -2, it now has 8 electrons total.
negative charge
all atoms generally do not have charge as the number of protons and number of electrons will be the same.
A sulfur ion can have a charge of either +2 or -2, depending on whether it gains or loses electrons. Specifically, sulfur can either gain two electrons to have a charge of -2 (S2-) or lose two electrons to have a charge of +2 (S2+).
If the atom is stable and neutral, it will have 14 electrons. If it has a positive charge it will have less electrons, and if it has a negative charge it will have more electrons.
