Multiple Choice
Which of the following statements is false?
A
If an electron has n = 2, it possesses only s and p orbitals.
B
Each orbital within a given atom can hold up to 2 electrons.
C
The second shell of an atom possesses d orbitals.
D
A set of f orbitals can hold a maximum of 14 electrons.
E
The first energy level contains only s orbitals.
Verified step by step guidance1
Understand the quantum number 'n': The principal quantum number 'n' indicates the energy level of an electron in an atom. For n = 1, only s orbitals are present. For n = 2, both s and p orbitals are present.
Review the capacity of orbitals: Each orbital can hold a maximum of 2 electrons, regardless of the type of orbital (s, p, d, or f).
Examine the second shell (n = 2): The second shell contains s and p orbitals, but not d orbitals. D orbitals start appearing from the third shell (n = 3) onwards.
Consider the f orbitals: A set of f orbitals consists of 7 orbitals, and since each can hold 2 electrons, they can collectively hold a maximum of 14 electrons.
Analyze the first energy level (n = 1): The first energy level contains only s orbitals, as p, d, and f orbitals are not present at this level.
