Feb 11, 2021 · Periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number. When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in the same column (group) have similar properties.

Periodic Classification Of Elements: The study of the Periodic Classification of elements is one of the most important and basic aspects of chemistry.It is essentially used to classify all the elements in groups. It helps us to approach a systematic study of various elements found in nature without which it would have been impossible to study the Periodic Table.

This was because early chemists did not recognise that "mineral alkali" (Na 2 CO 3, sodium carbonate, coming from deposits in the earth) and "vegetable alkali" (K 2 CO 3, potassium carbonate, derived from wood ashes) are distinct from each other. Potassium was discovered by Sir Humphry Davy (GB) in 1807. The origin of the name comes from the Arabic word qali meaning alkali (the origin of the symbol K comes from the Latin word kalium).

Elements that have similar chemical properties are grouped in columns called groups (or families). As well as being numbered, some of these groups have names—for example, alkali metals (the first column of elements), alkaline earth metals (the second column of elements), halogens (the next-to-last column of elements), and noble gases (the last column of elements). Sodium and cesium are both elements in Group 1. They have the same number of valence electrons and similar chemical properties. For example, they both explode in water. however, cesium reacts more violently in water than sodium.
