MODERN PERIODIC LAW

PROPERTIES OF THE ELEMENTS

DEPENDS ON THEIR ATOMIC

NUMBERS

WHEN ELEMENTS ARE ARRANGED IN

THE ASCENDING ORDER OF THEIR

ATOMIC NUMBER THERE IS A

REPETITION OF THEIR PROPERTIES

AT FIXED INTERVALS

MODERN PERIODIC TABLE

IT WAS PUT FORWARD BY MOSLEY

THERE ARE 7 PERIODS AND 18 GROUPS

ELEMENTS IN A SAME GROUP HAVE

EQUAL NUMBER OF ELECTRONS

ELEMENTS IN A GROUP SHOW SIMILIAR

PROPERTIES

NUMBER OF SHELLS OF N ELEMENT IS

EQUAL TO THE PERIOD NUMBER

Periodic Table: The three broad Classes

Main, Transition, Rare Earth

VALENCY VALENCY IS THE COMBINING

CAPACITY OF ELEMENTS.IT IS EQUAL TO THE NUMBER OF VALENCE ELECTRONS

IT IS THE NUMBER OF ELECTRONS DONATED, ACCEPTED OR SHARED

REPRESENTATIVE ELEMENTS

SHOW PERIODIC REPETITION OF ELECTRONIC CONFIGURATION

THERE ARE ELEMENTS BELONGING TO DIFFERENT CATEGORIES LIKE METALS, NON-METALS AND METALLOIDS

THERE IS REPRESENTATION FOR ELEMENTS IN VARIOUS PHYSICAL STATES

SIMILIAR PROPERTIES ARE EXHIBITED WITHIN THE GROUP

TRANSITION ELEMENTS

THE ELEMENTS IN GROUPS

ALL ARE METALS

THROUGH PERIODS

PERIOD NUMBER IS EQUAL TO TOTAL NUMBER OF SHELLS IN THE ATOM

IN SEVENTH PERIOD THE ELEMENTS THAT COME AFTER LANTHANUM ARE

CALLED LANTHANONES

IN THE SEVENTH PERIOD ELEMENTS THAT COME AFTER ATINIUM ARE

CALLED ACTINONES
