The distance traveled by the electron is expressed as:
In 1 second, the distance traveled by the electron is:
y = vavt
y = (2.20 × 106)(1) = 2.20 × 106m
The radius of the electron's orbit:
r = d/2 = (1.0 × 10-10)/2 = 5.0 × 10-11 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 1.0x10-10 in diameter.
(a) If the average speed of the electron in this orbit is known to be 2.20x106 m/s , calculate the number of revolutions per second it makes about the nucleus.
(b) What is the electron's average velocity?
