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 ____________________.
Well, it depends. Every isotope of a particular element has the same number of protons (by definition). All carbon isotopes have 6 protons; all nitrogen isotopes have 7 protons, all uranium isotopes have 92 protons, etc. Each element can have varying number of neutrons in addition to the protons that make the element. For carbon, for example, all carbon isotopes have 6 protons, but carbon-11 has 5 neutrons, carbon-12 has 6 neutrons, carbon-13 has 7 neutrons, carbon-14 has 8 neutrons, etc. Some of these isotopes are stable (carbon-12 and carbon-13); some are radioactive (carbon-11 and carbon-14). If you want to find out the number of protons and neutrons in an isotope, it is pretty straightforward.
