Silicon (Si) makes up around 15% of the Earth's mass while they come under trace elements (less than 0.01%) for their least availability in the human body.
While in the case of Nitrogen, it is present in the least amount (0.002%) in the earth's crust and its abundance is found at 3.3 % in the human body.
