Question 15 of 20
Assertion (A): When transitioning from left to right across a specific period, the metallic nature of the elements systematically decreases. Reason (R): The increasing effective nuclear charge strongly pulls the valence electrons inwards, making the atoms progressively less willing to lose electrons.
