Question

as the atomic size (increases/decreases) down a group, electronegativity (increases/decreases). this means the attraction for electrons is (higher/lower) and it will be more difficult to gain electrons, making the nonmetal (more/less) reactive. decreases / decreases / lower / more increases / decreases / lower / less decreases / increases / higher / less increases/ increases / higher / more

Explanation:

• Atomic size increases down a group due to more electron shells.
• Electronegativity (ability to attract electrons) decreases as the distance from the nucleus to the outermost electrons increases, weakening the attraction (lower attraction).
• With lower attraction for electrons, it's harder to gain electrons, so non - metals become less reactive.

Answer:

increases / decreases / lower / less
