Question

how could the modern periodic table remove anomalise of mendeleefs periodic table​

Answer 1

Modern Periodic Table:-

it consists 7 period and 18 group.

its base is atomic number.

Modern Periodic Table remove anomalies of mendeleev periodic table as:-

• as in mendeleev periodic table limitation arise of position of isotopes because they have different masses but of same elements and his table is depends on atomic mass. but in Modern Periodic Table atomic number is the base of the table show this problem solved.
• another problem of Mendeleev table is abnormal pairs which is cleared by Modern Periodic Table due to atomic number as the base of the table.
• the problems of mendeleev mostly corrected by Modern Periodic Table due to atomic base as a base of the table .
