The number of neutrons in the nucleus, as you may have gathered from the above example, can however change, and we call atoms of the same element with different numbers of neutrons "isotopes". Sometimes these isotopes are stable, but often they are not and eventually decay. Discovery of ...
The first twenty representative elements consist of elements that have the same or different number of corresponding protons and neutrons in their respective nucleus. The baseline of the neutronic periodic table of the elements is comprised of nine elements within the first twenty representative elements...
To understand the science behind this, it’s imperative to first comprehend certain basic concepts, such as isotopes, half-lives and radioactive decay. To being with, when atoms of the same element have a different number of neutrons, they’re known as isotopes. Isotopes of Hydrogen (P...
Neutrons have no electric charge and are found in the nucleus along with protons. The number of neutrons in an atom can vary, resulting in isotopes of an element. For example, carbon-12 has six neutrons, carbon-13 has seven neutrons, and carbon-14 has eight neutrons. Despite different num...

Elements usually have more than one isotope; that is, some atoms of an element will have different numbers of neutrons in the nucleus but the same number of protons. Some elements have an atomic weight given as a range, showing the extremes within which the average atomic weight is typically...

1: An isotope is an atom of any element with the same number of protons and electrons as all the other atoms of this particular element, but with a different atomic mass (and number of neutrons). 2: AMU- Atomic Mass Unit(s) 3: IUPAC- International Union for Pure and Applied Chemistry...

the number of protons in the nucleus changes, and the atom is transformed into one of a different element. The half-life of a radioactive isotope is the time required for half of any amount of theisotopeto disintegrate by radioactive decay. The common modes of decay of radioactive isotopes...
