Question:
Which of the following elements has the highest atomic number?
Which of the following elements has the highest atomic number?
Show Hint
The atomic number of an element increases with the addition of protons to its nucleus, so check periodic tables for the latest elements.

- Uranium
- Neptunium
- Plutonium
- Rutherfordium
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The atomic numbers of the elements are:
- Uranium (U) has an atomic number of 92.
- Neptunium (Np) has an atomic number of 93.
- Plutonium (Pu) has an atomic number of 94.
- Rutherfordium (Rf) has an atomic number of 104.
Thus, Rutherfordium has the highest atomic number among the options.
Therefore, the correct answer is: \[ \boxed{(D) \, \text{Rutherfordium}} \]
- Uranium (U) has an atomic number of 92.
- Neptunium (Np) has an atomic number of 93.
- Plutonium (Pu) has an atomic number of 94.
- Rutherfordium (Rf) has an atomic number of 104.
Thus, Rutherfordium has the highest atomic number among the options.
Therefore, the correct answer is: \[ \boxed{(D) \, \text{Rutherfordium}} \]
