No. Every question has 4 options and there is no timer, so you can work at your own pace.

How do I choose the number of questions if it shows 0?

A question count of 0 means it isn’t set yet—select your preferred number of questions on the start panel before beginning.

What topics are included in “periodic trends and properties”?

Expect atomic radius, ionization energy, electronegativity, electron affinity (basic), metallic character, shielding, and general reactivity trends across periods and groups.

How hard is the Easy difficulty?

Easy emphasizes core trend directions and simple comparisons (e.g., which element has the larger radius) with minimal exceptions.

How is my score calculated?

Your score is based on how many questions you answer correctly; you can review which trend each question was testing to spot patterns in mistakes.

Periodic Table Trends And Properties Quiz

About this quiz

What you’ll practice

This quiz focuses on the big periodic trends—how properties change across a period and down a group—and how to use those patterns to make fast, accurate predictions.

Each question uses a 4-option multiple-choice format with no timer, so you can think through the trend instead of rushing.

Common pitfalls to avoid

A lot of missed questions come from mixing up direction (left vs right, up vs down) or forgetting key exceptions and definitions. Watch for wording like “largest,” “most metallic,” or “highest first ionization energy.”

Confusing atomic radius trends with ionic radius trends
Reversing electronegativity and metallic character directions
Forgetting that ionization energy generally increases across a period and decreases down a group
Treating reactivity trends the same for metals and nonmetals
Overlooking that shielding increases down a group, affecting attraction to the nucleus

Difficulty and length settings

Difficulty is balanced by starting with straightforward trend recognition on Easy, then (at higher settings) adding more subtle comparisons and multi-step reasoning.

If your question count is set to 0, pick a question total before you start; you can also change the difficulty level to match how confident you feel with the trends.
