- Pb
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The atomic numbers of the elements are:
- Po (Polonium) has atomic number 84.
- Pt (Platinum) has atomic number 78.
- Pr (Praseodymium) has atomic number 59.
- Pb (Lead) has atomic number 82.
Therefore, the element with the highest atomic number is Po (Polonium).
