Question

If elements L and M are from the same period and the atoms of L are smaller than the atoms of M, then compared to atoms M, atoms of L are most likely to:

• A. have a lesser positive charge in their nuclei
• B. exist in a lesser number of isotopes
• C. have a greater positive charge in their nuclei
• D. exist in a greater number of oxidation states
• E. exist in a greater number of isotopes

Answer 1

The correct option is C have a greater positive charge in their nuclei

Compared to atoms M, atoms of L are most likely to have a greater positive charge in their nuclei. This results in greater force of attraction between valence electrons and nucleus for L. This decreases the atomic radius for L.
