Periodic Trends - Questions
The Periodic Trends Concept Builder is comprised of 54 questions. The questions are divided into 18 different Question Groups and spread across three different activities. Questions in the same group are rather similar to one another. The Concept Builder is coded to select at random a question from each group until a student is successful with that group of questions.
There are three activities in the Concept Builder. Those three activities are differentiated as follows:
- Atomic Radius: Question Groups 1-6 ...Rank three elements according to their relative atomic radius.
- Ionization Energy: Question Groups 7-12 ... Rank three elements according to their relative ionization energy.
- Electronegativity: Question Groups 13-18 ... Rank three elements according to their relative electronegativity.
As indicate above, there are six Question Groups in each activity. Two of the Question Groups include elements located in the same period of the Periodic Table. Two of the Question Groups include elements located in the same group of the Periodic Table. And two of the Question Groups include two elements located in the same group with a third element located in the same period as the lowest element in the group.
The questions from each group are shown below. Teachers are encouraged to view the questions in order to judge which difficulty levels are most appropriate for their classes. We recommend providing students two or more options.
The Physics Classroom grants teachers and other users the right to print these questions for private use. Users are also granted the right to copy the text and modify it for their own use. However, this document should not be uploaded to other servers for distribution to and/or display by others. The Physics Classroom website should remain the only website or server from which the document is distributed or displayed. We also provide a PDF that teachers can use under the same conditions. We have included a link to the PDF near the bottom of this page.
