Question

value: 3
the trend for electronegativity on the periodic table is that electronegativity increases as you move across the periodic table from ______.
mark all correct answers
a. right to left
b. top to bottom
c. left to right
d. bottom to top

Explanation:

Electronegativity trends in the periodic table: across a period (horizontal row), electronegativity increases from left to right (as atomic radius decreases and effective nuclear charge increases). Down a group (vertical column), electronegativity decreases from top to bottom (as atomic radius increases). So the correct directions where electronegativity increases are left to right (across a period) and bottom to top (up a group, since moving up decreases atomic radius and increases electronegativity).

Answer:

c. left to right, d. bottom to top
