what is valency?what is the valency of sulphur?

Answer 1

In chemistry, valency is the power of an atom of an element to combine with other atoms measured by the number of electrons which an atom will give, take, or share to form a chemical bond. This is related to the number of spaces left in an atom's electron shells. The adjective describing an atom's valency uses a Greek prefix (sometimes such as mono, b\di, tri, tetra etc. for valencies of 1, 2, 3, 4.

Answer 2

Valency Of Sulphur

Answer 3

Valence Of Sulfur

Answer 4

Valence, also known as valency or valency number, is a measure of the number of chemical bonds formed by the atoms of a given element. The concept was developed in the middle of the nineteenth century in an attempt to rationalize the formulae of different chemical compounds. Although it has fallen out of use in higher level work with the advances in the theory of chemical bonding, it is still widely used in elementary studies where it provides a heuristic introduction to the subject.


sulfur has six valence

Answer 6

4 6

Answer 7

Elements, like sulphur, consists of atoms. Every atom consists basically, for the sake of simplicity, of electrons, protons and neutrons. Electrons have an arbitrarily negative charge and protons have an arbitrarily positive charge. Every atom should have an even number of electrons and protons, which should give it a neutral charge. In reality some atoms have more, or less, electrons than they should have. For one type of atom, this can vary from one molecule to another. If you put four Sulphur atoms together then the whole molecule usually has two extra electrons (Valence 2-), so if you add sulphur to say Magnesium, which has two electrons missing, then you get Magnesium Sulphate (MgSo4).

Answer 8

Sulphur's valence electrons? Should be 6, check Periodic Table

Answer 9

Valence is a way of stating how an atom will combine. It also is the number of electrons in the outer ring. Sulfur has 2 electrons in tahe first energy level, 2 in the lower energy level of the 2nd ring and 2 in the 2nd energy level of ring 2.Sulfur generally combines with a charge of -2, but it can have other valences.

Answer 10

the valency of sulphur is 2
