Which atom has the smallest number of neutrons?
A) Carbon - 14
B) Nitrogen - 14
C) Oxygen - 16
D) Fluorine - 19
E) Neon - 20
Nitrogen is apparently the correct answer, however I don't understand how that is possible as Carbon - 14 has 6 electrons, and Nitrogen - 14 has 7. Please help me

The nucleus of an atom consists of protons and neutrons (no electrons). A nucleus of a carbon-12 isotope contains six protons and six neutrons, while a nitrogen-14 nucleus comprises seven protons and seven neutrons. You perform a nuclear physics experiment in which you bombard nitrogen-14 nuclei with very high speed carbon-12 nuclei emerging from a particle accelerator. As a result of each such collision, the two nuclei disintegrate completely and a mix of different particles are emitted, including electrons, protons,...

Determine how many electrons there are in total in your body and what is the total electrical charge of these electrons. Keep in mind that most of the atoms in your body have the same number of electrons, protons and neutrons. Consider the average composition of the human body of 75 kilograms mass as: 65% Oxygen, 19% Carbon, 10% Hydrogen, 3% Nitrogen, 2% Calcium and 1% Phosphorus. The atomic number of Oxygen is 8 and its atomic mass is 16...
