Answer
The correct statement is:
c. The hydrogen atom has quantized energy levels
Work Step by Step
a. This statement is false. The size of an orbital is determined by its principal quantum number, so the \( 3s \) orbital is larger than the \( 2s \) orbital.
b. True. The Bohr model of the hydrogen atom has indeed been found to be incorrect. It was a stepping stone in the development of quantum mechanics, but it has limitations and does not fully describe the behavior of electrons in atoms.
c. True.
d. False. An orbital is not the same as a Bohr orbit. The Bohr model describes electrons orbiting the nucleus in specific, fixed paths, while orbitals are regions of space where electrons are likely to be found.
e. True. When $n=3$, we can have $l=0$ ($s$ orbital), $l=1$ ($p$ orbital) and $l=2$ ($d$ orbital).
