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. a What units does mvr have?
b. b What is this property called?
c. 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.
