The combining capacity of an atom is known as its valency. The number of bonds that an atom can form as part of a compound is expressed by the valency of the element.
The valence of hydrogen is 1.
a. Define valency and variable valency with examples.
b. If the valency of nitrogen is 3 and of hydrogen is 1. Write down the formula for ammonia?
Valency of hydrogen atom is:-
Hydrogen forms only one bond, valency of hydrogen is-
Valency of hydrogen is 1 and that of sulphur is 2. What should be the formula of hydrogen sulphide?
