!.....please answer me fast .....!

Answer 1

1 ...classification of elements and periodicity of properties

• doeberenier traids
•trends in physical and chemical properties
•ionization energy ...full description
•mendeleev periodic table
•modern periodic table
•diagonal relationship
• diff b/w Mendeleev and modern periodic table
•newland octave
____________________

2... structure of atom

•shapes of atomic orbitals
• Pauli's rule
• hunds rule
• diff b/w orbit and orbitals
• electronic configuration
• Bohr's model
•Rutherford's model
•aufbaus principal
•quantum no.
______________________

3...some basic concept

• all short defines
• empirical formula
______________________

4...history of chemistry

• read all topics becoz all are important !
