Ax As we move ACROSS the periodic table in a row, the electronegativity

Question

increases

B
decreases

Answer 1

As we move across a period in the periodic table from left to right, the electronegativity generally increases (Option A). This is because the number of protons in the nucleus increases, which enhances the positive charge and the attraction between the nucleus and the valence electrons, leading to higher electronegativity values.
