The valency of hydrogen is +1 because it has a tendency to lose an electron while combining with an Elelment. This gives it a positive valency.

Radical - positive and negative radical in chemistry?

Valency is the number of hydrogen atoms that can combine with [or displace] one atom of the element [or radical] to form a compound. For example, one atom of hydrogen combines with one atom of chlorine to form hydrogen chloride [HCl]; so, the valency of chlorine [chloride] is one. Similarly, the valency of the nitrate radical [NO3] in the compound nitric acid [HNO3] is 1, and the valency of the sulfate radical in the compound sulfuric acid [H2SO4] is 2. For elements that do not combine with hydrogen, the valency is the combining power of the element with another element whose valency is known. Valency may also be defined as the number of electrons that an atom donates or accepts to form the duplet state (i.e., 2 electrons in outermost shell) or octet state (i.e., 8 electrons in outermost shell). The valency of an element [or radical] is always a whole number. Elements [or radicals] with valency one are monovalent, those with valency two are divalent, and those with valency three are trivalent

How does valency of element with respect to hydrogen vary in a period?

in a period from left to right valency of elements with respect to hydrogen increases from 1 to 4 and then decreases upto 1 and with respect to oxygen increases from 1 to 7.

How does Cl2 having valency 0 react with H2 also having valency 0 to form HCl with covalent bond?

Valency relates to atoms not molecules. A valency of one means that an atom can form one bond. Chlorine has 7 electrons in its outer shell, so forming one bond achieves the octet, so it is said to have has a valency of one. In Cl2 there is a single bond. Hydrogen has just one electron in its outer shell so forming a bond gives it a full shell of two like helium, it therefore has a valency of one. In H2 there is a single bond. In HCL there is a single bond. Valency is an old idea, predating Lewis diagrams, octets, and energy levels. It was the number of hydrogen atoms an elemnt could bond to.
