According to Bohr's theory electron should move _ nearer to nucleus in an orbit of _ radii.
Correct answer: B. Faster, smaller
- A. Slower, smaller
- B. Faster, smaller
- C. Faster, bigger
- D. Slower, bigger
Explanation
Correct option is B.The answer is faster and smaller. According to Bohr's theory, the speed of an electron in an atom is inversely proportional to the radius of its orbit. This means that as the radius of the orbit decreases, the speed of the electron increases. The reason for this is that the electron is constrained by the electromagnetic force of the nucleus. The closer the electron is to the nucleus, the stronger the force, and the faster the electron must move to stay in orbit.The radius of an electron's orbit is also related to its energy level. The lower the energy level, the smaller the radius, and the faster the electron must move. This is because the lower energy levels are closer to the nucleus, and therefore the electromagnetic force is stronger.Therefore, if an electron moves nearer to the nucleus, it will be moving faster and have a smaller radius.

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.
