Valency of Nitrogen
Valency is defined as the number of electrons that must be gained or lost by an atom to get a stable electron configuration.
Electrons that are found on the outermost shell are called valence electrons and the number of valence electrons helps in finding the valency of an atom.
- The valencies of the elements of s and p-block elements of the periodic table are found using eight minus the number of valence electrons.
- In the d and f-block elements, we can find valency not only based on the valence electrons but also on d and f orbital electrons. The general valencies of d and f block elements are 2 and 3.
The valency of nitrogen in NH3 is - (a) 3 (b) 4 (c) 1 (d) 2
The valency of nitrogen in NH3 is 3. As nitrogen is a group 15 element it has 5 electrons in the outermost shell.
