2nd Chance Periodic Trends Quiz

As you move down a group on the periodic table atoms get bigger. This is because ____________.

• The atoms have more mass.

• The atoms have more protons.

• The atoms have more energy levels

• The atoms have more neutrons

₁₁Na, ₁₂Mg, ₁₆S and ₁₇Cl are elements in Period 3. Arrange the following atoms in order increasing atomic radius.

• Mg < Na < Cl < S

• Na < Mg< S < Cl

• S< Cl < N < Mg

• C < S < Mg < N

Which statement correctly and completely identifies a trend?

• Atomic radius decreases across a period and increases down a group.

• Electronegativity decreases across a period and decreases down a group.

• Ionization energy increases across a period and increases down a group.

• Ionic radius increases across a period and increases down a group.
