Periods and Groups in the Periodic Table
Chemistry ⇒ Atomic Structure and the Periodic Table
Periods and Groups in the Periodic Table starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Periods and Groups in the Periodic Table.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 10
Describe the trend in atomic size as you move from left to right across a period.
Describe the trend in metallic character as you move down a group.
Explain why elements in the same group have similar chemical properties.
