12 + 10 = 22 charge
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.
The number of electrons are required to predict the charge of the ion.
A sodium ion with 11 protons and 10 electrons has a net charge of +1 because the number of protons (positive charge) is greater than the number of electrons (negative charge) by 1.
The ion would have a positive charge equal to the difference between the number of protons and electrons. For example, if there are 10 protons and 8 electrons, the ion would be a 2+ charged ion.
9 protons
12 + 10 = 22 charge
The ion with 13 protons and 10 electrons would have a 3+ charge since there are more protons than electrons. Its formula would be Al3+, representing an aluminum ion with a 3+ charge.
The overall charge of an ion is determined by the difference between the number of protons (positive charge) and electrons (negative charge). In this case, there are 12 protons and 10 electrons, leading to a net positive charge of +2. The number of neutrons does not affect the overall charge of an ion.
+2
The electrical charge is +3; this is the isotope aluminium-28.
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-
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.
