Question

give advantages of modern periodic table

Answer 1

Hey dear,

Here is your answer

       The important advantages of the modern periodic table are given below :

i)This classification is based on the atomic number which is a more fundamental property of the elements.

ii)Since this classification is based on the atomic number and not on the atomic mass, the position of placing isotopes at one place is fully justified.

iii)It is easy to remember and reproduce.

iv)The systematic grouping of elements into four blocks; s, p, d and f has made the study of the elements more simple.

v)The position of some elements which were misfit on the basis of atomic mass is now justified on the basis of atomic number. For example, argon precedes potassium because argon has atomic number 18 and potassium has 19.

vi)The lanthanoids and actinoids which have properties different from other groups are placed separately at the bottom of the periodic table.

Answer 2

Answer:

Explanation:

Advantages of modern periofic table

,● Easy to study elrments in a systematic way.

● Easier to remember properties of elements on knowing their position.

● The nature of compounds formed by an element can be predicted by knowing their position.

● Many new elemwnts can be discovered using this table.

● Atomic masses of certain elements can be corrected based ob their positions in the Mendeleeff's periodic table.
