Q7 of 106 Page 383

Which of the following curves may represent the speed of the electron in a hydrogen atom as a function of the principal quantum number n?


The speed of an electron (v) is inversely proportional to the principal quantum number (n). Thus the v-n graph should be rectangular hyperbola.


Hence, option (c ) is the correct answer.
