The periodic table is a well-organized chart that contains all the known elements in the universe. These elements are ...
The noble gases (Helium, Neon, Argon etc ... Meyer was just four years older than Mendeleev, and produced several Periodic Tables between 1864-1870. His first table contained just 28 elements, ...
If an atom has 2 protons, that’s an atom of the element helium. If it has 7 protons, that’s nitrogen. But the logic of the periodic table also relies upon the number and organisation of electr ...
