Question

can any1 explain to me about the periodic table to me if its possible

Answer 1

Answer:

Explanation:

PERIODIC TABLE IS A TABULAR FORM OF REPRESENTATION OF ALL KNOWN ELEMENTS IN SUCH AWAY THAT ELEMENTS WITH SIMILAR PROPERTIES CAN BE CATEGORISED UNDER THE SAME ROOM.

PERIODIC TABLE HAS 18 GROUPS (HORIZONTAL) AND 7 PERIODS(VERTICAL). IT WAS FIRST GIVEN BY DMITRI MENDELEEV AND FURTHER IMPROVED BY HENRY MOSELEY.

PERIODIC TABLE HAS 118 ELEMENTS. ALONG A PERIOD THE NUCLEAR RADIUS OF ELEMENTS DECREASE.

DOWN A GROUP VALENCE ELECTRONS REMAIN SAME. PROPERTIES OF ELEMENTS DOWN A GROUP REMAIN ALMOST SAME BUT ALONG PERIOD

METALLIC PROPERTIES FIRST INCREASE AND THEN DECREASE.

PERIODIC TABLE HAS 18TH GROUP AS INERT GASES AND TWO SEPARATE COLUMS OF ACTINOIDS AND LANTHANOIDS.

REACTIVITY OF ELEMENTS  DECREASE DOWN A GROUP AND INCREASES AS WE GO UP IN A GROUP.

PERIODIC TABLE ALSO HOUSES SOME BORDERLINE ELEMENTS OR METALLOIDS WHICH ARE  BORON SILICON, GERMANIUM, ARSENIC, ANTIMONY, TELLERIUM AND POLONIUM.

ALL ELEMENTS IN MODERN PERIODIC TABLE ARE ARRANGED AS PER INCREASING ATOMIC NUMBERS OR PROTON NUMBERS BUT IN MENDELEEV PERIODIC TABLE ELEMENTS WERE ARRANGED AS PER INCREASING ATOMIC MASSES.
