7 Comments on Shielding or Screening Effect

There are many observable patterns in the physical and chemical properties of elements as we descend in a group or move across a period in the Periodic Table. The term periodicity is used to indicate that some characteristic properties occur in the periodic table after definite intervals, with a varying (gradual increase or decrease) magnitude. The periodic recurrence of elements having similar […]

Halogens

The five elements; Fluorine (F), Chlorine (Cl), Bromine(Br), Iodine (I) and Astatine (At) belonging to VII A Group of the modern periodic table are collectively referred as halogens. The last element Astatine is radioactive and is very short lived hence generally excluded from the study. The word halogen is derived from the Greek words Halos […]
