the net charge of a single sulfide ion should be 2- .... hope this helps\

The chemical formula starts out with the two ions, the calcium and sulfide ions. Calcium's ion is Ca2+, while the sulfide ion is S2-. Because the net ionic charge of a compound is zero, only one of each atom is needed to create calcium sulfide, which will be CaS.
The charge of ion selenide is 2-.
A net postive charge
the Net charge of Iron is actually +2
it would have a net negative charge.
Aluminum Sulfide (Al2S3). This is because Aluminum makes a +3 charge ion and Sulfur makes a 2- ion. Thus, the 2 and 3 for each balance it out to a net charge of 0.
Sodium chloride is neutral.
A "cation" carries positive (+) charge. An "anion" caries a negative (-) charge. The charge carried in may be single or multiple.
The charge is 2- and it obtains that because it has 6 valence electrons. It is willing to accept 2 more in the valence shell to satisfy the octet, and thus it becomes 2-.
A sodium atom has a net charge of zero. A sodium ion has a net charge of 1+.
Gained or lost electron(s).
net negative charge

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.
All ions have an electrical charge.
The charge of ion selenide is 2-.
