Atoms And Nuclei Question 417
Question: Which of the following statements are true regarding Bohr’s model of hydrogen atom
(I) Orbiting speed of electron increases as it shifts to discrete orbits away from the nucleus (II) Radii of allowed orbits of electron are proportional to the principal quantum number (III) Frequency with which electrons revolve around the nucleus in discrete orbits is inversely proportional to the principal quantum number (IV) Binding force with which the electron is bound to the nucleus decreases as it shifts to outer orbits Select correct answer using the codes given below Code:
Options:
A) I and III
B) II and IV
C) I, II, and III
D) II, III, and IV
Show Answer
Answer:
Correct Answer: A
