Proteins
the subscript 2 after the H indicates that the hydrogen molecule contains two (2) atoms of hydrogen
The seventh most abundent element is potassium.
nitrogen
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
'NO' is not an element, and is therefore not found on the periodic table. The chemical NO is nitric oxide (aka nitrogen(II) oxide), a colorless gas at room temperature. If, however, you are referring to 'No', then it is the symbol for Nobelium, which is a synthetic, metallic, radioactive element with atomic number 102. It can be found in the actinide series.
Nitrogen is an element, so no other element contains nitrogen.
Nitrogen is an element that is usually found alone as the N2 molecule. It is not a compound.
Nitrogen is both an element and a molecule. In molecular form, Nitrogen forms a binary molecule N2 with a triple bond between the two Nitrogen atoms.
Nitrogen is an element, and two nitrogen atoms make up a nitrogen molecule.
At standard temperature, nitrogen is both an element and a molecule. It is an element because it has the same number of protons in the nuclei of all its atoms, and it is a molecule because it contains two separate atoms that are covalently bonded to one another and is electrically neutral
"element" (2 make up a molecule)
Nitrogen is an element. It is usually found as the molecule N2 not N. Therefore there are two atoms of nitrogen in this molecule.
N2 is the element nitrogen.
Nitrogen has 7 protons.
Nitrogen naturally occurs as a diatomic molecule (N2). Nitrogen, by itself, is an element.
The element is nitrogen (N). Nitrogen gas is a diatomic molecule (N2) and makes up approximately 78% of Earth's atmosphere.
