Here, we will discuss how ionic radii varies in the group and period. Let’s see the comparison of ionic radii with corresponding atomic radii. What is ionic radii The effective distance from the centre of the nucleus of the ion up to where it exerts its influence on its electron cloud. Or we can say […]

Here, we will discuss how the variation of atomic radii in group and period. We will study why do atomic radii increases in the group and decreases along the period. Variation of atomic radii in the group and period Why the at. radii decreases from left to right in a period But sometimes, we observe […]

Here, we will discuss about the different types of radii of atom and how to explain them. What is atomic radii : types of radii Atomic radii is the distance between the centre of the nucleus to the outermost shell containing electrons. What is covalent radii It is one half of the distance between the […]
