Periodic Table of The Elements

PERIODIC TABLE 

Alkali Metals – The alkali metals are so reactive that they are generally found in nature combined with other elements. All of the alkali metals share similar characteristics and properties, such as their color, softness, and melting points.
Alkaline Earth Metals – Alkaline earth metals in their pure forms are generally shiny and silvery and are very reactive. They rarely occur in their pure form.
Transition metal – Transition metals are lustrous and malleable, silvery, hard, and good conductors of heat and electricity.
Lanthanide – Elements found in the earth’s crust are called rare earth metals and Scientists referring to a lanthanide as a rare earth metal. They are used to make Strong magnets, Safety glasses etc..
Actinide – Some actinides are found in nature while others are man-made, They are all Radioactive.
Post-Transition metal (Base Metal) – Post- transition metals are soft (or brittle), have poor mechanical strength, and have melting points lower than those of the transition metals. Being close to the metal-nonmetal border.
 
Metalloid – Metalloids have a metallic appearance, but they are too brittle and only fair conductor of electricity. They behave mostly as nonmetals. They and their compound Used in alloys, catalysts, glasses, flame retardants, biological agents, Pyrotechnics, Optical storage and optoelectronics semiconductor, and electronics.
 
Polyatomic Nonmetal – Polyatomic nonmetals shows more metallic character. They are solid, brittle and low conductivity , mostly semi-lustrous Semiconductors with electronegativity values.
Diatomic Nonmetal (Halogen) – They are generally highly Insulating, Highly electronegative, non-reflective gases, Semi-lustrous, and a semiconductor. All of the elements in this elite group are gases.
Noble gas – Noble gases are typically highly unreactive, It makes them very suitable in applications where reactions are not wanted.
