the element nitrogen has an atomic number of 7 and an atomic mass of 14 how many protons, neutrons and electrons are in a atom o
Nat2105 [25]

Answer: By definition, if  the atomic number  = 7 , then there are 7 protons, 7 electrons, and 8 neutrons!

Explanation:

The atomic number is by definition the number of protons, positively charged particles, contained within the atomic nucleus. So if there are 7 protons, there MUST be 7 electrons, 7 negatively charged particles. Why? Because matter is electrically neutral, and positive and negative particles must be equal.

Electrons have negligible mass; the mass number depends on the number of protons contained within the nucleus, PLUS the number of neutrons. Given that we have  15  N , there must be 8 neutrons contained within the nucleus.  does this help?
