The structure of MODERN PERIODIC TABLE

MODERN PERIODIC TABLE is very important

The structure of MODERN PERIODIC TABLE MODERN PERIODIC TABLE is very important tool
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

ALKALI METALS

1A group of periodic table is called Alkali metals.

This group

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

Alkali metals are very soft metals, so they can be cut by knife

Cesium is most active metal in 1A group

Francium is radioactive metals
