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

the cyanide ion has a single negative charge, CN-
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 an atom who captured a single elektron is - or -1
Look at the periodic table. You see that the element that has 16 protons is Sulfur. Electrons have a single negative charge, while protons have a single positive charge, so an ion with 2 more electrons than protons will have a charge of 2-. So, the symbol of the ion would be S2- .
A net postive charge
One potassium ion is needed to balance the charge of one sulfide ion. This is because potassium has a +1 charge and sulfide has a -2 charge. Therefore, one potassium ion with a +1 charge will neutralize the -2 charge of one sulfide ion, resulting in a net charge of 0.
Sodium chloride is neutral.
The sulfide ion (S²⁻) obtains its charge by gaining two electrons. Sulfur, which has six valence electrons, tends to gain two additional electrons to achieve a stable electron configuration similar to that of the noble gas argon. This gain of electrons results in a net negative charge of -2, leading to the formation of the sulfide ion.
the cyanide ion has a single negative charge, CN-
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-.
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.
A "cation" carries positive (+) charge. An "anion" caries a negative (-) charge. The charge carried in may be single or multiple.
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.
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.
