Nitrogen
The element rubidium (Rb) as a single atom has thirty-seven protons.
Nitrogen has 7 protons.
The element with atom number seven: NitrogenNitrogen
nitrogen
For any periodic element, its atomic number correlates directly with its number of protons. Thus, an element with an atomic number of six has six protons, with an atomic number of seven, seven protons, and so on.
Elements are determined by their number of protons. Nitrogen has 7 protons but usually 7 neutrons as well. What you have here is a nitrogen isotope, an element with more or less neutrons than there are protons. Specifically, this is Nitrogen-15.
Nitrogen is the element with 7 protons. It is place din period -2 and group-15.
The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus of an atom. In this case, the element has 7 protons and 8 neutrons, so the atomic mass would be 7 + 8 = 15 atomic mass units.
Protons are protons, no matter what element they are in.
what element contains 16 protons? what element contains 10 protons?
Each chemical element has a specific number of protons; the number of protons is equal to atomic number of the element.
The element which has the smallest atomic number has the smallest number of protons. In this case, argon has a proton number of 18 (therefore it has 18 protons in each atom), but nitrogen has fewer protons - it has a proton number of just 7, meaning that it has seven protons per nitrogen atom.
