The electronegativity of elements on the periodic table tends to increase_______.

Question

Quizplus · Accepted Answer

The electronegativity of elements tends to increase from left to right across a period (row) on the periodic table because the number of protons in the nucleus increases, leading to a stronger attractive force for electrons. The electronegativity also tends to increase from bottom to top within a group (column) because the atomic size decreases, leading to a stronger attractive force for the electrons that are closer to the nucleus. Therefore, the best choice is C - from left to right, bottom to top.
