▪▪Formed elements----------
a) Outermost shell of these elements is incomplete. The number of electrons in the outermost shell is less than eight.
b) Inner shells are complete
c) s-and p-block elements except inert gases are called normal or representative elements.
eg:hydrogen, oxygen, carbon, nitrogen, etc
▪▪radioactive elements---------
an element subject to spontaneous degeneration of its nucleus accompanied by the emission of alpha particles, beta particles, or gamma rays. All elements with atomic numbers greater than 83 are radioactive. Naturally occurring radioactive elements include radium, thorium, and uranium. Several radioactive elements not found in nature have been produced by the bombardment of stable elements with subatomic particles in a cyclotron.
eg:technetium, radium,uranium,dubenium,etc
