1. What does an element's position on the periodic table tell you about the element?

Plenty of details regarding its affinity to other elements for example, its likelihood to / or not to go into some chemical reactions untouched, its groub and subgroub, its surface charge and number of electrons

The periodic table is a systematic arrangement of the elements. They are arranged according to their atomic number, the number of protons (which in the case of atoms is also the number of electrons) of each atom. Some of the properties of the elements can be predicted given their location in the periodic table.
