Nitrogen and hydrogen combine to form ammonia with the formula, NH3. Write the
combining capacity of nitrogen and hydrogen from this information
Write the chemical formulae of the following compounds using suitable valency:
a) Potassium sulphate
b) Ammonium phosphate
Answers
Answer:
Valency is the measure of the combining capacity of atoms or molecules. Therefore, it is the capacity of an atom of a single element to react and combine with particular numbers of atoms of another element.

The Concept of Valency Explained
Electrons in an atom are arranged in different orbitals (shells) represented as K, L, M, N, and so on. The electrons present in the outermost shell/orbit of an atom are called valence electrons. The valence electrons take part in any chemical reaction because the outermost orbit usually contains more energy than the electrons present in other orbits.
According to the Bohr-bury scheme, the outermost orbit of an atom will have a maximum of 8 electrons. However, if the outermost orbit is completely filled then very little to no chemical activity is observed in the particular element. Their combining capacity becomes negligible or zero.
