1. The periodic table is an arrangement of all the elements known to man in accordance with their increasing atomic number and recurring chemical properties.
2.They are assorted in a tabular arrangement wherein a row is a period and a column is a group.
3.Elements are arranged from left to right and top to bottom in the order of their increasing atomic numbers.
4.Elements in the same group will have the same valence electron configuration and hence similar chemical properties.
5.Elements in the same period will have an increasing order of valence electrons, therefore, as the energy level of the atom increases, the number of energy sub-levels per energy level increases.
