Distance covered in one revolution, C = πd = π(1.06 × 10−10) = 1.06π × 10−10 m
The planetary model of the atom pictures electrons orbiting the atomic nucleus much as planets orbit the Sun. In this model you can view hydrogen, the simplest atom, as having a single electron in a circular orbit 1.06×10−10 m in diameter.
(a) If the average speed of the electron in this orbit is known to be 2.20×106 m/s, calculate the number of revolutions per second it makes about the nucleus.
(b) What is the electron's average velocity?
