Calcium is the correct answer as rain water is hard water and contains calcium and magnesium. Nitrogen is not correct although it is abundant in nature because it is not much soluble in water even plants need symbiotic bacteria for nitrogen intake.
We can easily see white layer on leaves after raining because of calcium contents in rain water and it's not nitrogen.

I thing its Nitrogen because rainwater dose contain small amount of nitrus and nitric acids as N2 is the most abundant gas in atmosphere thus when lighting sticks it causes nitrogen to react with oxygen to form NO2 N2O5 etc. Which then mix with water vapor to form acids.

I accept that the ocean water is rich in calcium but it does not evaporated by sun light (because of this we obtain salt) so the correct answer is nitrogen.

We never study in previous classes about rain water contains calcium, mostly it contains acids so that is called acid rain.

It's nitrogen contents because calcium can't be present in rainwater. It is present in soil not in rainwater.

Rain water also contain some mineral of magnesium and calcium so it increases calcium a little.

Rain water doesn't have low minerals like nitrogen, phosporous. It has only calcium content.

In rainwater large amount of nitrogen present so it must be nitrogen nor calcium.

Nitrogen, because no any part containging Calcium in the rain water.

Rain water does not contain calcium in it. Its probably Nitrogen.
