Periodic Table Practice Tests

These Grade 10 Science practice tests develop understanding of periodic law, groups, periods, element families, metals, nonmetals, metalloids, valence electrons, atomic trends, ionization energy, electronegativity, and ion prediction.

Skills covered

  • Reading groups, periods, atomic number, metals, nonmetals, metalloids, and the staircase boundary
  • Recognizing alkali metals, alkaline earth metals, transition metals, halogens, noble gases, and chalcogens
  • Explaining trends in atomic radius, ionization energy, electronegativity, metallic character, shielding, and nuclear charge
  • Using valence electrons and simple electron arrangements to locate elements and predict reactivity
  • Predicting common ions, ionic formulas, element comparisons, and periodic-table limitations

How to use these practice tests

Locate the element first, then identify its group, period, family, and valence-electron pattern. Use the direction of a periodic trend to compare elements and justify predictions about ions or compounds.

1. QuestionMultiple choice

What is the periodic law?

Please select an answer first.

Correct answer: A

The correct answer is Element properties repeat in a predictable pattern when elements are arranged by atomic number..

  1. Locate the element or trend: Determine whether the question asks about a group, period, family, valence electrons, atomic size, ionization energy, electronegativity, or reactivity.
  2. Apply the periodic relationship: The periodic table organizes elements by increasing atomic number and reveals repeating property patterns.
  3. Check the prediction: The correct answer is Element properties repeat in a predictable pattern when elements are arranged by atomic number..

The periodic table organizes elements by increasing atomic number and reveals repeating property patterns.

2. QuestionMultiple choice
