I can't wait for school it's going to be a good day besides it't friday what can go wrong
yes what can go wrong??
What!! I forgot to study
oh no! I forgot that we had a test
don't forget about the science unit test today class make sure you studied
were did you come from!!
I'm here to help you with your test. Your are supposed to know compounds, element's , and molecule's
That makes a little sense
An element is a pure substance that is composed of a single type of Atom. And a Atom is a tiny particle that makes up all matter. For example C which is carbon is known as an element.
now time to learn about a compound. A compound is a pure substance composed of two or more different elements. for example, C and O which is known as carbon and oxygen is known as a compound
okay I think we are ready for our test!!
And lastly but not least a molecule is a group of two or more atom's held together by chemical bonds. For example is you add two hydrogen and one oxygen which is known as a molecule. Also (N2) is a molecule and an element.
