An ion that has more electrons than protons has a negative charge.
35
The number of electrons are required to predict the charge of the ion.
It has 3 more protons than electrons. Protons are 1+ and electrons are 1-. So the charge on the hypothetical ion would be 3+
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.
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 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 charge on a carbonate ion is -2; therefore, the ion has two more electrons than protons.
An ion that has more electrons than protons has a negative charge.
A net postive charge
9 protons
A sulfur ion with a charge of 2- has gained 2 electrons, giving it a total of 16 protons and 18 electrons. This results in an overall charge of -2 due to the extra negatively charged electrons.
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.
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.
There are 19 protons in an ion with 18 electrons and a -1 charge. The -1 charge indicates that the ion has gained an extra electron, resulting in one more electron than 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).
