Metal:
A metal is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity. These metals are located to the left of the heavy zigzag line on the periodic table.
Metalloid:
Metalloids have properties of both metals and nonmetals. These metalloids are located along the heavy zigzag line on the periodic table.
Non metal:
A non-metal is no luster, with poor electrical and thermal conductivity. These metals are located to the right of the heavy zigzag line on the periodic table
Main group :
The main group is the group of elements whose smallest or first members are represented.
These are helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, and fluorine as arranged in the periodic table of the elements.
