+2: 26 - 24.
A neutral atom has an equal number of protons and electrons. Protons are positively charged, and electrons are negatively charged. Therefore if you have an ion with a -1 charge, it has one extra electron. So your ion has 85 protons.
Remember.. I f there are more electrons than protons in an ion the charge will be negative. Here there is a -4 charge because the electrons are higher than the protons, if it were the opposite the charge would be +4.
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.
35 protons, 36 electrons
A neutral atom does, because the negative and positive charges balance to even out the charge. It is the opposite of an ion.
An ion with 15 protons and 18 electrons has a net charge of +3 since it has 3 more electrons than protons. This ion would be classified as a cation.
Electrons have a negative charge. Thus, a species with more electrons than protons will have a negative charge. The compound with 20 protons and a minus two charge must therefore have 22 electrons.
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.
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 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).
There are 11 protons in an ion with 10 electrons and a -1 charge. The charge of an ion is defined by the difference between the number of protons and electrons. In this case, since the ion has a -1 charge, it means there is one more electron than the number of protons.
A neutral atom has an equal number of protons and electrons. Protons are positively charged, and electrons are negatively charged. Therefore if you have an ion with a -1 charge, it has one extra electron. So your ion has 85 protons.
The charge of an ion is determined by the difference between the number of protons and electrons. In this case, the ion has 34 protons and 36 electrons, resulting in a net charge of 2- since there are 2 more electrons than protons.
