Basic Atomic Structure

This quiz was designed by a New Zealand high school teacher to help her Year 9 students with the topic of atomic structure. If you are studying for Year 11 this quiz is not covering everything you need to know; Year 11's should be getting 100% in this quiz!

Atomic structure is an important topic because knowing what is inside atoms can help us figure out in Year 10 and 11 why certain atoms have particular properties/behave in certain ways/bond with certain other atoms.
