This ion will have a charge of -1. The atomic number is the number of protons in the atom's nucleus. A neutral atom will have a number of electrons equal to the atomic number, which is the number of protons in that nucleus. Since you have an extra electron your atom has a negative charge of one electron's worth, or minus one, which is 1.6 x 10-19 coulombs.
The ion would have a positive charge if it has more protons than electrons. Since protons have a positive charge and electrons have a negative charge, an excess of protons will result in an overall positive charge for the ion.
A net postive charge
If there are more electrons than protons, then the ion charge is negative. If there are more protons than elections, then the ion charge is positive.
The total charge on an oxygen ion with 8 protons and 10 electrons is +2, because oxygen normally has 8 protons and 8 electrons, resulting in a neutral charge. Adding 2 extra electrons gives a net charge of -2.
The charge on an ion is equal to the number of protons minus the number of electrons. In this case, the ion would have a charge of +2 (75 protons - 77 electrons).
Ion 2+=====
+2
The charge of an ion is determined by the difference between the number of protons (positive charge) and electrons (negative charge). In this case, the ion would have a charge of +1 since it has 1 more proton than electrons.
i think it depends how many electrons it has. then you do something like subtract the electrons from the protons. electrons are negative, protons are positive.
The ion would have a positive charge if it has more protons than electrons. Since protons have a positive charge and electrons have a negative charge, an excess of protons will result in an overall positive charge for the ion.
The particles that affect the charge of an atom or ion are electrons and protons. Electrons have a negative charge and protons have a positive charge. The number of electrons and protons in an atom or ion determines its overall charge.
An ion that has more electrons than protons has a negative charge.
A net postive charge
If there are more electrons than protons, then the ion charge is negative. If there are more protons than elections, then the ion charge is positive.
The charge on an ion is equal to the number of protons minus the number of electrons. In this case, the ion would have a charge of +2 (75 protons - 77 electrons).
If an ion has more electrons than protons, it would have a negative charge. The charge of the ion would be equal to the excess of electrons over protons.
The total charge on an oxygen ion with 8 protons and 10 electrons is +2, because oxygen normally has 8 protons and 8 electrons, resulting in a neutral charge. Adding 2 extra electrons gives a net charge of -2.
