Question

I can't understand the chapter periodic classification of elements. ​

Answer 1

why it's very simple

Answer 2

See it's really very simple . If I want to learn it more perfectly. Always see the modern periodic table . In that chapter the periodic table is main . Also try to have a complete periodic table. I mean the periodic table which is complete not in the book. Because in book the given periodic table is not much clear .
