First of all, if we know the atom symbol (or name), let's say H, we can open any periodic table and search for Hydrogen. If the periodic table is complete just scroll up and read the number on the top (from 1 to 18). In the case of Hydrogen the group number is 1. However there is a lot of funny facts about Hydrogen that most people don't know.

An element's first ionization energy is the energy required to remove the outermost, or least bound, electron from a neutral atom of the element. On the periodic table, first ionization energy generally decreases as you move down a group. This is because the outermost electron is, on average, farther from the nucleus, meaning it is held less tightly and requires less energy to remove.

james harrington asked the Naked Scientists: Dear Dr. Chris, I'm a GCSE chemistry student (taking it through to AS and A level) and i've always been puzzled why hydrogen is in group 1 of the periodic table (with the alkali metals). I asked my teacher if hydrogen is a metal and he gave me a straight no. I did some research and found a few science magazine articles.
