question 17
as atomic radii decreases, electronegativity and ionization energy
word bank:
decreases increases stays the same increases stays the same decreases
blank 1:
blank 2:

Explanation:

• Electronegativity: As atomic radii decrease, the nucleus has a stronger pull on electrons (due to reduced electron - electron shielding and increased effective nuclear charge), so electronegativity increases.
• Ionization energy: When atomic radii decrease, it is more difficult to remove an electron (because the electron is closer to the positively - charged nucleus and more strongly attracted), so ionization energy increases.

Answer:

Blank 1: increases
Blank 2: increases
