The expression for the radius of nth orbit of hydrogen atom was derived by?
Correct answer: B. Bohr
- A. Planks
- B. Bohr
- C. Rutherford
- D. Einstein
Explanation
According to Planck's theory, energy is not emitted or absorbed continuously, but in discrete packets or quanta. The Bohr radius, denoted by "a₀", is a physical constant representing the most probable distance between the electron and the nucleus in a hydrogen atom or hydrogen-like ion. The Bohr radius is equal to 0.52917721067 x 10^-10 meters, or approximately one-fifth of a nanometer The theory proposed that atoms consist of a small, dense positively charged nucleus at the center, surrounded by negatively charged electrons that orbit the nucleus. Einstein proposed the theory of relativity

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
