Magnesium

Vedclass · Answer

(C) Chlorophyll is a complex organic molecule that contains a central magnesium atom $(Mg^{2+})$ coordinated within a porphyrin ring structure.When chlorophyll is burnt,the organic components (carbon,hydrogen,oxygen,nitrogen) are oxidized and released as gases like $CO_2$,$H_2O$,and $NO_x$.The magnesium atom,being a metal,does not volatilize and remains in the ash as magnesium oxide $(MgO)$ or other magnesium salts.Therefore,magnesium is the element that remains.
