The secondary valency is non-ionisable and cannot be precipitated because it form coordinate bond with the metal atom. For example in coordination compound Cl4 , the secondary valencies are 6 for Pt4+, so in this Pt4+ is satisfied by chlorine and ammonia molecules. What is the secondary valency of thisRead More →
the primary valency is non-directional because the metal atom works towards satisfying both its primary and secondary valencies. A negative ion satisfies the primary valency. On the other hand, a negative ion or neutral molecules satisfy secondary valencies. What is meant by primary valency is Ionisable? Primary valency is knownRead More →
As in all its compounds and its elemental forms, carbon is tetravalent, which means that it always forms four bonds. What carbon is tetravalent? The valency of carbon is four because one carbon atom requires 4 electrons to achieve the nearest inert gas configuration. Thus, we can say that carbonRead More →
valence, also spelled valency, in chemistry, the property of an element that determines the number of other atoms with which an atom of the element can combine. Introduced in 1868, the term is used to express both the power of combination of an element in general and the numerical valueRead More →
Valency is the combining capacity of an element. The total number of electrons in the outermost shell varies from 1 to 8 there for the combining capacity will always be 1,2,3,4,5,6,7 or 8. Therefore valency is always positive. What does the positive and negative number of valency indicate? the wordRead More →

Now the number of electrons shared by nitrogen in ammonia is 3 only, one with each of the 3 hydrogen atoms while the remaining two electrons remain as a lone pair. Since the number of electrons shared by nitrogen is 3, hence the valency of Nitrogen in ammonia is 3.Read More →
