When the first ionisation energy is plotted against the atomic number, the peaks in curve are occupied by:
Open in App
Solution
The correct option is B Noble gases
Generally, the first ionization energy increases as we go across a period. Hence, the maximum peaks in the curve are occupied by rare gases. This is because they require more energy to disturb the stable configuration that they have attained.
