The speed of the electron in the Bohr theory of hydrogen is A)proportional to n. B)proportional to n². C)inversely proportional to n. D)inversely proportional to n².

Question

Quizplus · Accepted Answer

According to the Bohr theory of hydrogen, the speed of the electron is inversely proportional to n, where n is the principal quantum number. As n increases, the electron moves to higher energy levels, farther away from the nucleus, and hence the speed decreases. Therefore, option C is the correct choice. The other options are not valid expressions for the speed of the electron in the Bohr theory.
