1.	The statement given below are the postulates of various atomic models . Arrange them in their chronological order Fine structure is due to the presence of subshells in the main energy level The size of an atom is much larger than the size of its nucleus As long as the electron is present in a particular orbit , its energy remains constant Negative charged particals are uniformly spread inthe lump of positive charge
Answer» 4,3,2,1 2,3,4,1 4,2,3,1 3,4,2,1 Solution :Negatively charged particles are uniformly spread in the lump of positive charge (Thomson s MODEL). The SIZE of atom is much LARGER than the size of its nucleus (Rutherford's model). As long as the electron is present in a particular orbit, its energy remains constant (BOHR's model). Fine structure is due to the presence ofsubshells in the main energy LEVEL (Sommerfeld s model).
