Vedclass · Answer

(A) The apatite family of minerals,such as fluorapatite,has the general formula $Ca_5(PO_4)_3(F, Cl, OH)$.Phosphorus $(P)$ is a main component of the apatite family.The first four group $15$ elements are Nitrogen $(N)$,Phosphorus $(P)$,Arsenic $(As)$,and Antimony $(Sb)$.The first ionisation enthalpy values for these elements are:$N: 1402 \ kJ \ mol^{-1}$$P: 1012 \ kJ \ mol^{-1}$$As: 947 \ kJ \ mol^{-1}$$Sb: 834 \ kJ \ mol^{-1}$Since Phosphorus is the element in question,its first ionisation enthalpy is $1012 \ kJ \ mol^{-1}$.

First ionisation enthalpy values of first four group $15$ elements are given below. Choose the correct value for the element that is a main component of apatite family $:$
