Which of the following statements is TRUE?
A) We can sometimes know the exact location and speed of an electron at the same time.
B) All orbitals in a given atom are roughly the same size.
C) Since electrons have mass, we must always consider them to have particle properties and never wavelike properties.
D) Atoms are roughly spherical because when all of the different shaped orbitals are overlapped, they take on a spherical shape.
E) All of the above are true.

Question

Quizplus · Accepted Answer

Atoms are considered roughly spherical because the combination of the various orbitals, each with its unique shape, results in an overall spherical distribution of electron density. This is especially true when considering many-electron atoms where the distribution of electrons in different energy levels and orbitals leads to a spherical average shape.
