You can make another search to find the answers to the other puzzles, or just go to the homepage and then select the pack and the level number in which you are stuck on. Atomic number (number of protons in the nucleus): 12 2. Our website offers mainly answers to Pixwords (in French language). For example, element 120 has the temporary name unbinilium. The chemical symbol for Magnesium is Mg. Atomic Mass of Magnesium Atomic mass of Magnesium is 24.305 u. Isotopes are nuclides that have the same atomic number and are therefore the same element, but differ in the number of neutrons. For stable elements, there is usually a variety of stable isotopes. The key difference between calcium and magnesium is that the calcium appears as a dull grey metal with a pale yellow tint whereas the magnesium appears as a shiny grey metal. But we decided to add answers to Mystic Words since a lot of our users have contacted us to do so. This alkaline earth metal has atomic number 12 and element symbol Mg. The … It has a role as a cofactor. There are also tutorials on the first thirty-six elements of the periodic table.
