MODERN PERIODIC TABLE is very important tool for chemists and scientists.
It is easy to predict the properties of elements by using periodic table.
In PERIODIC TABLE all elements are arranged from left to right and top to bottom in
order of increasing atomic number
Atomic number is the order number of
elements which is indicated by the number of
protons of element.
Atomic number = proton number

8. MODERN PERIODIC TABLE

Nowadays, there are 118 chemical elements. 94 of them are occurred naturally, where
the remaining 24 elements are synthetic elements
Simple periodic table contains symbol, atomic number and relative atomic weight of
chemical elements

29. ALKALI METALS

1A group of periodic table is called Alkali metals.
This group contains H (hydrogen), Li (Lithium), Na
(sodium), K (potassium), Rb (Rubidium), Cs
(Cesium), Fr (Francium)
But hydrogen is
nonmetals, it is
located in 1A group
because of its
electronic
configuration
Alkali metals are most active metals. They can
react even with air and water, so they are stored
under the kerosene
Cesium is most active
metal in 1A group
Alkali metals are very soft metals, so they can be
cut by knife
Francium is radioactive
metals
