Question

what are the overall trends in electronegativity?
in general, electronegativity tends to decrease
from bottom to top and right to left on the periodic table.
from bottom to top and left to right on the periodic table.
from top to bottom and left to right on the periodic table.
from top to bottom and right to left on the periodic table.

Explanation:

Electronegativity measures an atom's ability to attract bonding electrons. On the periodic table, atomic size increases top to bottom (more electron shells), weakening the nucleus's pull on electrons, so electronegativity decreases. Electronegativity increases left to right as nuclear charge rises (same shell, stronger pull), so the reverse (right to left) means a decrease.

Answer:

from top to bottom and right to left on the periodic table.
