He wrote it almost 30 years before Thomson discovered the electron, close to 45 years before Rutherford found the nucleus of an atom and over 50 years before scientists determined that the proton and neutron made up the nucleus of the atom! The original periodic table was created by Russian chemist Dmitri Mendeleev. The same is true as you travel down the periodic table. Chemists use the symbol of an element when referring to it in a compound or equation, so these are important to know.Īs you move from left to right on the table, the atomic number and atomic mass of the element increases. This is because the symbol is typically based on the Latin name for the element, which in the case of lead is plumbum. Some are easy, like O for Oxygen some make less sense, like Pb for Lead.

This code is accepted internationally to remove language barriers when discussing chemical compounds.
Sometimes this can vary if there are isotopes of the element, so the atomic mass given on the periodic table is an average of those varying weights.

Plus as technology grows, our ability to more clearly define those relationships grows as well. Just like our human relationships, these elemental relationships can be defined, or shown, in different ways. they all are.īut remember that the periodic table is a way for us to visually show the relationships between the elements. One periodic table will have four different blocks, like the one below.Īnd yet another periodic table will have columns, or groups, of different colors, like the one below.Īnd there are even more options for visual representations of the periodic table than the four we have shared here.Īdd to that the differences in where and how the inner transition metals - the lanthanides and actinides - are shown. Plus, elements have been added and named over the years, poor hydrogen doesn't seem to know what group it belongs to, and selenium is sometimes a nonmetal, sometimes a metalloid!Īll this begs the simple question - which periodic table is the right one? One periodic table will have only three colors, like the one below.

One periodic table will be full of color, dividing elements into families and giving them names, like the one below. But it can be a bit confusing because it appears as if there are so many different visual options out there.
