Since the anion has a 2- charge, it must have two more electrons than protons. The number of protons is 18 - 2, which is 16. Since the element has 16 protons, it is element 16, which is sulfur (S).
A sodium ion has a charge of 1+ because it has lost one electron, leaving it with one more proton than electrons. Protons have a positive charge, whereas electrons have a negative charge, so losing an electron results in a net positive charge for the sodium ion.
the net charge of a single sulfide ion should be 2- .... hope this helps\ Nigguuuhzz
A net postive charge
The net charge of a silver ion (Ag+) is +1 because it has lost one electron.
Many different chemical species can form an ion with a plus 1 change. The most common example of cations of this type are the alkali metals, such as sodium and potassium.

The net charge is the total amount of charge that the ion will have. So you will find out the charge of each group and add them all together for the net charge.
A sodium ion has a charge of 1+ because it has lost one electron, leaving it with one more proton than electrons. Protons have a positive charge, whereas electrons have a negative charge, so losing an electron results in a net positive charge for the sodium ion.
A 6A ion likely refers to an ion with a charge of +6. This means the ion has lost 6 electrons, resulting in a net positive charge of 6.

A net postive charge
The net charge of a silver ion (Ag+) is +1 because it has lost one electron.
The element is vanadium (V) because it has 23 protons. With 18 electrons and a net charge of 3 plus, it would have lost 3 electrons, resulting in a net charge of +3. The number of neutrons (28) does not affect the charge or identity of the element.
Cations are ions with net positive charge. Anionshave net negative charge.
