A)There is no difference between the orbitals of the modern model of the atom and the orbits of the Bohr model of the atom.
B)A 1s orbital can be represented as a two-dimensional circle centered around the nucleus of an atom.
C)A 2p orbital is smaller than a 3p orbital.
D)The p orbitals always come in sets of four.
E)The d orbitals always have three lobes.

Question

Quizplus · Accepted Answer

A 2p orbital is indeed smaller than a 3p orbital because as the principal quantum number (n) increases, the size of the orbital also increases. This means a 3p orbital, which is in the third energy level, is larger than a 2p orbital, which is in the second energy level.
