nitrogen 15 number of protons neutrons and electrons
Nitrogen is the 7th element on the periodic table. One isotope of nitrogen has atomic mass 15. In a neutral nitrogen-15 atom there are _____ protons, _____ neutrons, and ______ electrons. I don't just need the answer but just an explanation of how you got that.This should be really simple.n a neutral atom, number of electrons = number of protons Therefore number of electrons = 7 Number of protons + number of neutrons = atomic mass Or number of neutrons = atomic mass-number of protons = 15 - 7 = 8 Ans: 7 protons, 8 neutrons, and 7 electrons ____________________.
