🔴 ATOMIC RADIUS - Trends in Periodic Table || Chemistry for Class 11 in HINDI 

In this Chemistry video in Hindi we explained the trend in the atomic radius in periodic table. As we move from left to right in the periodic table the atomic radius, in the same period, reduces. And as we move from top to bottom in a group, the atomic radius increases. When we move from left to right the positive charge in the nucleus increases, hence the atomic radius reduces. When we move down a group, as the principal quantum number increases the electron comes in a new shell, hence the atomic radius increases.
We also talked about the ionic radius. For cation it reduces and for anion it increases. For isoelectronic species, the entity with higher number of protons has the less ionic radius.
