By mass Oxygen
by number of atoms- hydrogen by weight - oxygen The most abundant element in the human body is oxygen. About two thirds (65%) of the human body is oxygen by mass. The most abundant metal in the human body is calcium.
Earth has oxygen and silicon which make 75% while in the human body oxygen, hydrogen, and carbon make up over 90% of it. In short its oxygen.
Iron. Existent in the blood.
Oxygen (apex)
OXYGEN.
Oxygen, hydrogen & Argon.In order, large percentages of Nitrogen, Oxygen followed by trace amounts of Argon are the most abundant elements in the earth's atmosphere.
the most abundant gas of the atmosphere is nitrogen with high percentage 78.09
The water is not so abundant in the atmosphere and is very variable (o-1 %).
calcium is!
Nitrogen and Oxygen
Oxygen, not quite Nitrogen makes up 78% of the earth's atmosphere.
Oxygen is O and nitrogen is N.
Oxygen, hydrogen & Argon.In order, large percentages of Nitrogen, Oxygen followed by trace amounts of Argon are the most abundant elements in the earth's atmosphere.
Nitrogen
That element is Oxygen by 46.6%
the most abundant gas of the atmosphere is nitrogen with high percentage 78.09
nitrogen is the most common element in the earths atmosphere
Nitrogen, which is an element. It has atomic number 7 on the Periodic Table of Elements.
The water is not so abundant in the atmosphere and is very variable (o-1 %).
calcium is!
Nitrogen & oxygen.
Oxygen is the most abundant element in the earth's crust and is not in the boron family. Aluminum is in the boron family and is the third most abundant element in the earth's crust. Refer to the related link for a list of the 10 most abundant elements in the earth's crust and their percentages.
