oxygen is the most abundant on the earth crust followed by silicon and then aluminum,buh in the air its nitrogen followed by oxygen and then co2 and found in minute quantities are the rare gases
Nitrogen is d most abundant element in air while oxygen is d most abundant element on d earth crust.
please don't confuse urselves.
nitrogen is the most abundant element in the air (ATMOSPHERE),yes.
HOWEVER.... oxygen is the most about elements on earth (LITHOSPHERE)... check page 370, newschool chemistry.
Oxygen is d answer...nitrogenay contain 78% of air..but oxygen is d most abundant in d earth crust
OXYGEN is d most abundant element on d earth crust-- go and read about oxygen
nitrogen is the most abundant gas in air but when we talk about the aircrust, oxygen is the most abundant.
what is causing the confusion is inability to differentiate between air and aircrust, just read about oxygen and nitrogen and Know the differences between them
Oxygen ~46.6%
Silicon ~27.7%
Aluminum ~8.1%
Iron ~5.0%
Calcium ~3.6%
In the atmosphere is different from earths crust
My school is Correct
C is the most correct option
Key point: Most abundant element on *earth's crust* is Oxygen
Most abundant element in air *Nitrogen*
nitrogen is the most abundance element on earth's crust not oxygen,because nitrogen takes 60% before any other gas like that oxygen follows
