Question

difference between mandelevs periodic table and modern periodic table. give big answer, don't give answer of two or three lines.

Answer 1

In Madleev periodic table properties of elements are periodic function of their atomic masses while in modern periodic table properties of elements are periodic function of their atomic number

Answer 2

Hello Sister☺

⭐Mendeleev 's Periodic Table :-

1. It is based On Atomic masses of elements.

2.it Does not tells about why similar chem.properties occur after a interval .

3.It does not explain Periodicity in Properties of elements.

4.It has a number of defects .


⭐Modern periodic table :-

1. It Was Based on Atomic no.of elements.

2.It tells us in group elements have similar properties due to same valence electron

3.Same balence electrons are repeated So , Properties are also repeated.

4. There are no defects in Modern Periodic table.

It Helps U ✌☺
