How many neutrons does the neutral atom have?

Answer 1

It varies depending on the atom but basically there are the same number of neutrons as there are protons. Helium has two protons, two electrons, and two neutrons.

The difference between the Atomic Mass and the atomic number equals the atom's number of neutrons. Consider hydrogen, for example. Standard hydrogen has no neutrons, just one proton. Deuterium is an isotope of hydrogen with one neutron, and tritium (which is unstable) has two neutrons. Carbon 12 has six protons and six neutrons, but carbon 14 (which is unstable) has six protons and eight neutrons. As you move up the Periodic Table, nuclei tend to have more neutrons than protons. 92 U 238, for example, has 146 neutrons.

Answer 2

It depends on the atom itself. An oxygen atom might have eight neutrons (with eight protons) while uranium has 142 (with 90-odd protons). Its the difference in the atomic mass and atomic number for neutrons.

Answer 3

7 neutrons, 7 protons and 7 electrons in Nitrogen.

Answer 4

It depends on the atom itself. An oxygen atom might have eight neutrons (with eight protons) while uranium has 142 (with 90-odd protons).
