Modern periodic tables list the information of the number of protons, neutrons, and electrons in each element, including magnesium (Mg). This element has 12 protons and 12 electrons for a neutral charge of 0. Magnesium 25 has 25 total nucleons (which includes both protons and neutrons). This means that an atom of Mg 25 has 13 neutrons.
The number of neutrons in an atom of an element is not always the same. The stable common Isotope of Mg is Mg 24 which has, as the name suggests, 24 total nucleons – this would mean that it has 12 neutrons. The amount of neutrons in an atom of an element is what make it an isotope. The term generally refers to atoms of the same element but with different numbers of neutrons. There are also some elements which occur in nature as only one isotope, meaning that the number of neutrons and protons of those elements are always the same. That is not the case for cadium – its different isotopes have different numbers of neutrons.
All of this information can be seen in different periodic tables available online. They are a useful tool to quickly find out the number of neutrons, protons, and electrons in a given element.
