How can you find an element?

I'm assuming you mean "how can you find an element on the periodic table?" The periodic table is strategically placed.

The periodic table from left to right is sorted by increasing atomic number. The periodic table from top to bottom is sorted by increasing number of energy levels (the levels in which the electrons are in).
