And the X-Ray Fluorescence XRF Spectrometer . To find the concentration of elements ( (potassium (K), calcium (Ca), chromium (Cr) ,Magnesium(Mn),Iron(Fe),Nickel(Ni), copper(cu), Zinc (Zn),Lead (pb) ,Bromine (Br) , Rubidium (Rb), Strontium (Sr)) was found the bonds ( Alkenes ) - C = C - , It was found that concentration Calcium in honey pumpkin is grater than in bitter melonphysics
