6. How is the modern periodic table arranged? Now we sort elements by their number of protons, or “atomic number,” which determines an atom’s configuration of oppositely charged electrons and hence ...

At present, the periodic table has 118 elements. As discussed earlier, Mendeleev introduced the concept of atomic numbers based on the properties of the elements. At that time, the structure of the ...

so an iron atom is much larger than the carbon atom, which in turn is larger than a hydrogen atom, and so on. The periodic table is atableof all the elements in the universe; indeed, the periodic ...
