Chemistry Exam Review : Atoms, Elements, Compounds

I DID NOT cover everything, for full coverage: study the ppt and worksheets again (I'm still here if there are any parts that confuses you)
If I made mistake, or something isn't clear enough, feel free to point it out and I'll review it. 👍
Thank you for watching, sorry its not the best; this is my first video after all...
