Question

what appears to be the trend in electronegativity as you move down a group?
increasing
decreasing
remains the same

Explanation:

Electronegativity is a measure of an atom's ability to attract electrons in a chemical bond. As we move down a group (vertical column) in the periodic table, the atomic radius increases because new electron shells are added. The valence electrons are further from the nucleus, and the shielding effect from inner electrons increases, reducing the nucleus's effective pull on the valence electrons. This leads to a decrease in electronegativity.

Answer:

B. decreasing
