Which of the following statements about atomic orbitals is false? a. A 1s orbital is spherically symmetrical. b. An atomic orbital may contain zero, one, or two electrons. c. A 2s orbital and a 2p orbital are equal in energy. d. A 2px orbital and a 2py orbital are equal in energy. e. A 2p orbital is not spherically symmetrical.

Expert Solution

False statement

Ans: c. A 2s orbital and a 2p orbital are equal in energy

Both the principal quantum number (n) and azimuthal quantum number (l) determines the energy of the atomic orbitals. In the same n^th orbit, orbital with higher l value will have higher energy. So 2p (n=2, l=1) is higher in energy than 2s (n=2, l=0).

Remaining options are all true.

s-orbitals are spherically symmetric.

An atomic orbital can hold a maximum of 2 electrons. It can have zero/one/two electrons.

2px, 2py and 2pz all have same energy, they are degenerate.

2p orbitals have dumb-bell shape along the respective axes. So they are not spherically symmetric.
