Periodic Trends Mixed Practice

Which of the following will have a larger radius than zinc?

• Gallium

• Aluminum

• Magnesium

• Strontium

Which of the following will have a lower ionization energy than scandium (Sc)?

• Helium (He)

• Titanium (Ti)

• Calcium (Ca)

• Magnesium (Mg)

As atoms of elements in group 16 are considered in order from top to bottom, the electronegativity of each successive element....

• decreases
• increases
• remains the same
• none of the above

Which atom has the largest atomic radius?

• potassium
• rubidium 
• francium
• cesium

As you move down a column of the the periodic table, atomic radius increases. This is because ____________.

• the atoms are more massive

• the atoms have more protons

• the atoms have more occupied energy levels

• the atoms have more neutrons

Which statement correctly and completely identifies a periodic 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.

As you move across the periodic table from left to right, the atomic radius decreases.  This is because - 

• the number of protons increases, so attraction to electrons increases
• the number of energy levels increases
• the number of electrons increases
• the atomic mass increases

Which of the following period 6 elements has the lowest first ionization energy?

• Rn

• Cs

• Os

• Tm

Which of the following will have a lower first ionization energy than scandium (Sc)?

• Helium (He)

• Titanium (Ti)

• Calcium (Ca)

• Magnesium (Mg)

Which of the following will have a higher ionization energy than arsenic (As)?

• Gallium (Ga)
• Neon (Ne)
• Antimony (Sb)
• Germanium (Ge)
