Now are known 118 chemical elements and more than 3 000 isotopes and isomers.
Most elements contain a mixture of isotopes, which are atoms of the same element with different numbers of neutrons. Isotopes can have different properties but behave similarly in chemical reactions due to their identical number of protons.
The answer you are looking for is "isotopes" HOWEVER, please note you CAN NOT HAVE 2 elements with the same number of PROTONS. This is because the number of protons DEFINES an element. Isotopes are the SAME element but with differing numbers of neutrons.
144Nd and 145Nd are both isotopes of neodymium. Neodymium-145 is considered observationally stable. Isotopes are elements whose atoms differ in the number of neutrons.
Isotopes are elements that differ in the number of neutrons they have. Isotopes of an element have the same number of protons in their nuclei but different numbers of neutrons, resulting in varying atomic weights.
There are a bit more than 100 elements however there are far, far more than 100 millions compounds, each day more compounds are produced, there are a lot of compounds with unknown structure, not having official names. So the ratio is much bigger than 1 to a million

An isotope is an atom; a chemical element may be formed from one or more isotopes having the same number of protons and electrons but with different number of neutrons.
Since you have isotopes of elements. Isotopes are elements with different number of neutrons hence why the different atomic masses for the same elements.
It is simply that among period 2 elements, oxygen (8) is one of the elements which has the largest number of isotopes, among period 4 elements, calcium (20) has the largest number of isotopes, and among period 5 elements, tin (50) has the largest number of isotopes. In fact tin has the largest number of isotopes overall.
During some radioactive explosion/exposure the atoms combine and if they stay stable they from with extra amounts of protons. Isotopes are when two or more elements have the same number of protons, but different number of neutrons.
Isotopes differ in the number of neutrons they possess.
Many elements have different isotopes: 1) Carbon - Carbon 12, Carbon 14 2) Hydrogen - Protium, Deuterium, Tritium 3) Chlorine - Chlorine 35, Chlorine 37 etc
The atomic number of the isotopes of an element is identical; the mass number is different.
