The atomic mass/weight of an element is in the neutrons
since we all know that nitrogen has 7 electrons and 7 protons (the number of electrons= the same number of protons that's why an atom is neutral)
electron + protons= neutrons( mass/weight number)
7 + 7 = 14 💯
if u know ur 20 to 30 elements well u will know that nitrogen is the 7 th
having 7 electrons 👍
