The sulfur atom requires two additional electrons in order to achieve a noble gas configuration, or octet. When it does so, it contains two more electrons than protons and becomes an ion with a charge of 2-.
It has a charge of 2-, S2-
It has a charge of 2-, S2-
Sulfide ion is S2- ion it is formed from the element sulfur gains two electrons. Sulfur belongs to group 16, period 3.
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 group 2 elements form ions with a 2+ charge. For example, Mg2+ and Ca2+. The group 16 elements form ions with a 2- charge. For example, O2- and S2-.
It has a charge of 2-, S2-
It has a charge of 2-, S2-
Sulfide is divalent ion. it is S2-
It has a charge of 2-, S2-
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-).
Ferrous is the traditional name of the iron (II) ion. (Fe 2+) The formula for ferrous sulfide is FeS since sulfur has a charge of -2.
Sulfide ion is S2- ion it is formed from the element sulfur gains two electrons. Sulfur belongs to group 16, period 3.
S for sulfur because the number of protons tells you the atomic number with is 16 and 16 is sulfur. The electrons means it is an ion with two more electrons than protons. The neutrons have no charge but add mass to the element.
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 group 2 elements form ions with a 2+ charge. For example, Mg2+ and Ca2+. The group 16 elements form ions with a 2- charge. For example, O2- and S2-.
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- .
The Sulfide ion, S2-, is isoelectronic with Cl-
