35 Compared to the metals in Period 2, the nonmetals in Period 2 have

(1) lower first ionization energies and lower electronegativity values

(2) lower first ionization energies and higher electronegativity values

(3) higher first ionization energies and lower electronegativity values

(4) higher first ionization energies and higher electronegativity values

Solution: Ionization energy and electronegativity increase as we go from the left to the right across a Period on the Periodic Table. Metals are to the left of the staircase on the Periodic Table and nonmetals are to the right. If you do not remember the trend for ionization energy and electronegativity, you can also compare the value of elements in Table S on the Reference Table.

Answer: 4
