How is a sulfide ion formed from a sulfur atom?

How is a sulfide ion formed from a sulfur atom?

The valence shell (the 3s and 3p sublevels) contains six electrons, but it needs eight to become stable. Therefore a sulfur atom will gain two electrons to form the sulfide anion with a charge of 2− , with the symbol S2− .

What is the formula of the sulfide ion?

Sulfide (British English also sulphide) is an inorganic anion of sulfur with the chemical formula S2− or a compound containing one or more S2− ions. Solutions of sulfide salts are corrosive….Sulfide.

How does a sulfur ion differ from a neutral sulfur atom?

1 Answer. Elemental sulfur, or sulfur in a neutral element has 6 electrons associated with it, and is therefore neutral. S2− ions has 8 electrons, and therefore bears a 2- minus charge.

What is the ion that forms from the sulfur atom?

Sulfide

Why does an aluminum ion have a +3 charge?

As Al has 3 valence electrons as M(3) so it tends to lose electrons then after losing these 3 electrons it has 10 electrons and 13 protons, and 10 electrons are neutralized by 10 protons out of 13, and the further excess 3 protons out of 13 appear as +3 charge.

What is zinc most commonly used for?

Most zinc is used to galvanise other metals, such as iron, to prevent rusting. Galvanised steel is used for car bodies, street lamp posts, safety barriers and suspension bridges. Large quantities of zinc are used to produce die-castings, which are important in the automobile, electrical and hardware industries.

What is zinc used for medically?

Zinc is used by some people to help with the common cold or lung infections, malaria, or asthma. It may help with wound healing, ulcers, acne, and skin infections. Some people will use zinc to help with age-related problems like macular degeneration or Alzheimer disease. Others will use it to help with loose stools.
