Explain why elements that are in the same group of the Periodic Table tend to show similar chemical behavior.

Question:

Element

Element in same column or group of periodic table have similar chemical properties as their atoms have same valence electrons. For example lithium has 1 valence electron and sodium and potassium also has 1 valence electron.
