How many protons are in a neutral stable nitrogen atom
Graph of isotopes by type of nuclear decay. Some nitrogen atoms have 15 nucleons in the nucleus and therefore have an atomic mass number of
Nuclear Magic Numbers
All of these radioisotopes are short-lived, with the longest-lived one being nitrogen with a half-life of 9. All of the others have half-lives below 7.
Most of the isotopes with atomic mass numbers below 14 decay to isotopes of carbonwhile most of the isotopes with masses above 15 decay to isotopes of oxygen. The shortest-lived known isotope is nitrogen, with a half-life of about 2. Nitrogen is one of two stable non- radioactive isotopes of the chemical element nitrogenwhich makes about Nitrogen is one of the very few stable nuclides with both an odd number of protons and of neutrons seven each.

However, this is not the case. The line curves upwards.How to find the number of protons, neutrons and electrons in atoms and ions
Stable isotopes of the heavier elements top right of the graph have more neutrons than protons. For example, Gold is stable. It contains 79 protons and neutrons.
The neutrons in a nucleus can be thought of as acting as a kind of glue to hold the nucleus together. The positively charged protons are in a very confined space but would rather not be, due to the fact that they repel each other. However, protons and neutrons are all attracted to each other as a result of another force - the strong nuclear force see below.
The neutrons don't contribute any repulsive effects because they are neutral. So having more neutrons around can help to hold the nucleus together.
Neither Here nor There
All of the elements with an atomic number greater than 82 have only unstable isotopes. This is the strong nuclear force.
The strong nuclear force binds protons and neutrons together to make the nucleus. Neutrons and protons are made from quarks see page A isotope is an element that has same atomic number but different atomic mass compared to the periodic table.
Every element has a proton, neutron, and electron.
Nuclide, Atomic Number, mass number
To determine the number of neutrons in an element you subtract the atomic number from the atomic mass of the element. The principal factor for determining whether a nucleus is stable is the neutron to proton ratio.
Carbon has three isotopes that scientists commonly used: P ratio therefore is 6: This is a stable ratio that lies on the Belt of Stability. Identify the number of neutron, protons, total nucleons and N: Elements that have atomic numbers from 20 to 83 are heavy elements, therefore the ratio is different.
The ratio is 1. Neutrons help to separate the protons from each other in a nucleus so that they do not feel as strong a repulsive force from other. The graph of stable elements is commonly referred to as the Band or Belt of Stability.
