The Chronological order of statements given by various scientists is as follows:
Conclusion Statement: Option (c) is the correct answer.
An element has an atomic number of 13 and an atomic mass of 27. (a) How many electrons are there in each atom of the element? (b) How are these electrons distributed in the various energy levels?
(a) How many electrons are there in each atom of the element ?
(b) How are these electrons distributed in the various energy levels ?
Arrange the following statements given by various scientists in chronological order:1) Calculation of energy and radius of the orbit 2) Atoms of the same elements are identical in all respects 3) Calculation of the diameter of the nucleus and the atom 4) Assumption of thinly spread positively charged mass
The statements given below are the postulates of various atomic models. Arrange them in chronological order.(1) Fine structure is due to the presence of subshells in the main energy level(2) The size of an atom is much larger than the size of its nucleus(3) As long as the electron is present in a particular orbit, its energy remains constant(4) Negatively charged particles are uniformly spread in the lump of positive charge
