Q1. Which group of elements in the periodic table shows the highest first ionization potential? Elements in the:
Answer: Right-hand top corner
Explanation: First ionization energy increases across a period (left to right) and decreases down a group; elements in the top-right corner (noble gases/halogens like He, Ne, F) have the highest values.
