These first 20 elements of the periodic table run across all the 8 groups in the table starting from the group on element down to the group eight elements or what is generally known as the inert gases or rare gases. As students of chemistry, understanding the chemical behavior, properties and reactions of the first twenty elements of the periodic table is the first step in having an authoritative knowledge of chemistry and its applications in all of its branches. It is very pertinent that every science student at least at the ordinary level stage understand how the in the periodic table are groped and arranged in periods and groups and what properties inform the groupings of these elements. I have since learned that importance of the first 20 elements in scientific study and exploits and have devised a methodology of memorizing these first 20 elements without must task to my brain power!
