1. What is the maximum number of electrons that can be accommodated in a d subshell?
A.
2
B.
6
C.
10
D.
14
Correct Answer:
10
Explanation:
A d subshell contains five orbitals, and each orbital can hold two electrons. Therefore, its maximum capacity is 5 × 2 = 10 electrons.
2. How many orbitals are present in a d subshell?
A.
1
B.
3
C.
5
D.
7
Correct Answer:
5
Explanation:
A d subshell consists of five orbitals. Since each orbital can accommodate two electrons, the d subshell can hold up to 10 electrons.
3. If each orbital in a d subshell holds two electrons, how many electrons can five d orbitals hold?
A.
5
B.
8
C.
10
D.
12
Correct Answer:
10
Explanation:
There are five orbitals in a d subshell, and each holds two electrons. Thus, the total capacity is 5 × 2 = 10 electrons.
4. Which electron capacity corresponds to a completely filled d subshell?
A.
2 electrons
B.
6 electrons
C.
10 electrons
D.
14 electrons
Correct Answer:
10 electrons
Explanation:
A completely filled d subshell has all five of its orbitals occupied by two electrons each, giving a total of 10 electrons.
5. A d subshell can contain a maximum of how many electron pairs?
A.
2 pairs
B.
3 pairs
C.
5 pairs
D.
7 pairs
Correct Answer:
5 pairs
Explanation:
A d subshell has five orbitals. Each orbital can contain one electron pair, so a filled d subshell contains five electron pairs.
6. Which statement about the capacity of a d subshell is correct?
A.
It can hold a maximum of 2 electrons.
B.
It can hold a maximum of 6 electrons.
C.
It can hold a maximum of 10 electrons.
D.
It can hold a maximum of 14 electrons.
Correct Answer:
It can hold a maximum of 10 electrons.
Explanation:
The d subshell has five orbitals, with two electrons allowed in each orbital. Therefore, its maximum capacity is 10 electrons.
7. How many electrons are needed to completely fill one d subshell?
A.
4
B.
8
C.
10
D.
12
Correct Answer:
10
Explanation:
Complete filling requires two electrons in each of the five d orbitals, so 5 × 2 gives 10 electrons.
8. A d subshell containing 5 orbitals has a total electron capacity of:
A.
5 electrons
B.
7 electrons
C.
10 electrons
D.
15 electrons
Correct Answer:
10 electrons
Explanation:
Each of the five orbitals in a d subshell can hold two electrons. Hence, the total capacity is 10 electrons.
9. What is the maximum number of electrons that can occupy the five orbitals of a d subshell?
A.
5
B.
10
C.
15
D.
20
Correct Answer:
10
Explanation:
Because each orbital can accommodate two electrons, five d orbitals can accommodate a maximum of 5 × 2 = 10 electrons.
10. A fully occupied d subshell is represented by which electron count?
A.
d2
B.
d6
C.
d10
D.
d14
Correct Answer:
d10
Explanation:
The d subshell has five orbitals and can hold 10 electrons when fully occupied. Therefore, a filled d subshell is represented as d10.
