Answer:

calcium exist as compound becase it cant exist in independent form

Answer 2

Answer:

Explanation: existence of metals in environment depends upon their reactivity the more reactive they will be the more the compound they will form

elements which lies above hydrogen in reactivity series generally exist in compound forms or as ore containing some other impurities

for example- iron which lies above hydrogen in reactivity series also exist as Fe₂O₃, Fe₃O₄,etc. will gold platinum which are lowest in reactivity series generally exist in elemental form and only some of them exist in compound form.
