When atomic SULPHUR forms the bond with another atom (or atoms) in which it becomes the ion SULPHIDE, it accepts two electrons from the outer shell of the other atom(s); giving it a relative negative charge. Examples are Iron (II) [old name Ferrous] Sulphide - FeS - or Potassium Sulphide - K2S [ionic potassium has a single positive charge - it donates a single electron when it forms an ionic bond].
(U.K. Sulphur/sulphide = U.S. Sulfur/sulfide!)
The Sulfide ion, S2-, has a 2- charge because a lone atom of sulfur has 6 outer shell electrons, but it is more stable to have 8 outer shell electrons. So sulfur may gain 2 electrons (electrons have a -1 charge) to achieve this full outer shell.
A lone neutral sulfur atom (S) has six outer shell electrons. However, this is not a particularly stable configuration.
The most stable configuration would be an outer shell of 8 electrons. To achieve this setup a sulfur atom may take two additional electrons from some other substance, typically a metal. Since each electron carries a 1- charge the overall charge of the ion will be 2-.
This is the most stable monatomic ion of oxygen, because it makes the oxide ion isoelectronic with the noble gas neon.
Because of the Mayan calendar.
I hope my professional opinion helped!
because it has a -2 charge
BeSO4 Sulfate is a polyatomic ion = SO4 and this has a charge of -2 and Beryllium usually has a charge of +2
It is called the Sulphide ion
A strontium ion has a charge of +2
The Sulphate ion
Barium forms a +2 charge, along with all other group 2 metals.
-2 is the most common charge (sulphide ion).
The charge that sulphide has will depend in its state. Sulphide in itself does not have any charge but sulphide ion has a negative charge.
Sulfide is divalent ion. it is S2-
The charge of the molybdenum ion is +2.
A strontium ion has a charge of +2
Sulfur can form the sulfide ion (S2-) and the disulfide ion (S22-) on its own. When combined with oxygen it can form the sulfate ion (SO42-) and sulfite ion (SO32-).
BeSO4 Sulfate is a polyatomic ion = SO4 and this has a charge of -2 and Beryllium usually has a charge of +2
No. The oxide ion has a -2 charge.
It is called the Sulphide ion
The formula for a chromate ion is CrO4-2, and its charge is -2.
The charge is 2+.
