The more protons and neutrons that are in the element and isotope electrons are negligible in terms of mass.
This element is calcium. It is the fifth most abundant element in the Earth's crust and makes up more than 3 percent of the crust. It reacts with water and belongs to the 2nd group of the periodic table.
Nitrogen makes up more than three fourths (about 78%) of the air we breathe, while oxygen comprises about 21%.
Nitrogen makes up 78% of the Earth's atmosphere.
This notation does not represent a valid chemical compound or element. It seems to be a combination of a subscript and numbers that do not align with standard chemical notation. Can you provide more context or clarify your question?
Nitrogen makes up about 78% of the Earth's atmosphere.
Beryllium is the alkaline earth element with the least massive atoms.
In the same column (group) but in a row below the chemical you start with.
CARBON
Down in any group of the perodic table.
two or more different elements
It is nitrogen and it makes more than 78% of the air.
... more massive (it has more mass).... more massive (it has more mass).... more massive (it has more mass).... more massive (it has more mass).
Nitrogen
helium
Because more than 99 % from the mass of an atom is concentrated in the nucleus (protons + neutrons).
Virtually any atom of element more massive than oxygen(including carbon and many more elements your body consists of) was created in supernovae explosions.
