About this quiz

What you’ll practice

Element families are the shortcuts to predicting behavior on the periodic table, and this quiz helps you use them confidently. You’ll connect group names to properties like valence electrons, common charges, and typical reactivity.

Expect a mix of recall and reasoning: some questions focus on identifying a family, while others ask you to infer properties from group position. The format is simple—4 options per question and no timer—so you can focus on accuracy.

Difficulty and question settings

Difficulty is balanced by blending straightforward group facts (like alkali metals vs noble gases) with trend-based prompts that require comparison across periods and groups. Choose your preferred question count and difficulty before you start to tailor the session to quick drilling or full-length revision.

Recognize major families: alkali metals, alkaline earths, halogens, noble gases, and transition metals
Predict common ion charges and valence electron patterns by group
Compare reactivity trends within a family (up vs down a group)
Distinguish metals, nonmetals, and metalloids using location and properties
Avoid common mix-ups between group number, period number, and electron shells

Common pitfalls to watch for

A frequent mistake is confusing “group” trends with “period” trends, especially for atomic radius, electronegativity, and ionization energy. Another is assuming every element in a column behaves identically—this is mostly true for main-group elements, but transition metals can vary more.

If you miss a question, use the explanation you’d give in class: name the family, state the valence electron count, then link it to charge and reactivity. That quick chain of reasoning makes the patterns stick.
