Problem
Consider the electron property given by the equation mvr , where m is the electron's mass, v its speed and r the radius of its orbit around the nucleus.
(a) What units does mvr have?
(b) What is this property called?
(c) Bohr proposed the idea that the angular momentum of an electron must be quantised.
- i What does the word *quantised* mean?
- ii Bohr's proposal was that angular momentum should be measured in units of 2πh , where h is Planck's constant, given as h=6.63×10−34 J s. Show that Bohr's proposal is dimensionally consistent.
