Question

question 5
which of the subshells below do not exist due to the constraints upon the angular momentum quantum number?

4p
4s
4f
4d
none of the above

question 6
the uncertainty principle states that ______.

there can only be one uncertain digit in a reported number
matter and energy are really the same thing
it is impossible to know anything with certainty
it is impossible to know how many electrons there are in an atom
it is impossible to know the exact position and momentum of an electron

Explanation:

Analyze subshell constraints

Using the Quantum Numbers and Atomic Orbitals knowledge points

$$
LATEXBLOCK0
$$

All listed subshells (\(4\text{p}\), \(4\text{s}\), \(4\text{f}\), \(4\text{d}\)) exist. Thus, "none of the above" is correct.

Define the uncertainty principle

The Heisenberg uncertainty principle states that it is fundamentally impossible to simultaneously know both the exact position and momentum of a particle (such as an electron) with perfect precision.

$$ \Delta x \cdot \Delta p \ge \frac{h}{4\pi} $$

This directly matches the option stating "it is impossible to know the exact position and momentum of an electron".

Answer:

Question 5

• 4p
• 4s
• 4f
• 4d
• none of the above (Correct answer)

Question 6

• there can only be one uncertain digit in a reported number
• matter and energy are really the same thing
• it is impossible to know anything with certainty
• it is impossible to know how many electrons there are in an atom
• it is impossible to know the exact position and momentum of an electron (Correct answer)
