Which of the following properties generally decrease along a period? (A) Ionization energy (B) Electron affinity (C) Metallic character (D) Valency

Answer: (c) Metallic character

Explanation

Along a period the electropositive character decreases, therefore the ionization energy, electron affinity and valency increases while metallic character decreases.The metallic property of an element reduces as we travel from left to right in the periodic table, according to the contemporary periodic table. This is because, as an atom moves from left to right over time, the amount of electrons and protons in the atom is predicted to rise, strengthening the nuclear force and making it more difficult to lose electrons. The group’s metallic aspect grows stronger as it progresses. Because the atomic radius grows as one moves down the group, it becomes simpler to lose electrons, resulting in a metallic nature.
