A Grade 9 Chemistry Quiz!

Atoms are the smallest and main building blocks of ordinary matter, and they join together to form molecules that make the objects around us. In 9th grade chemistry, we got to dive deeper into the makeup and the elements as a whole. Getting ready for that end year exam? Take up the test below and get to review all that we have covered so far.
