Matter is anything that takes up space and has mass.
All matter is made of atoms
What are atoms?The smallest amount of an element.
Atoms are the building blocks of matter, (sort of how bricks are the building blocks of houses.)

An atom has three parts:Proton = positiveNeutron = no chargeElectron = negative
The proton & neutron are found in the center of the atom, a place called the nucleus.
The electrons orbit the nucleus.

What are elements?A basic substance that can't be simplified (hydrogen, oxygen, gold, etc...)
What are Molecules?2 or more atoms that are chemically joined together (H2, O2, H2O, etc...)
Created by G.Baker www.thesciencequeen.net
What are compounds?• A molecule that contains more than one element (H2O, C6H12O6, etc...)

Summary:
Created by G.Baker www.thesciencequeen.net
Atoms combine to make Molecules
Molecules can be either elements(2+same type of atom) or compounds (2+ different atoms combined)
These all combine to make MATTER.
Video Break:Take five notes during the video. (write
down five interesting facts)https://www.youtube.com/watch?

Atomic Number:
Number of protons and it is also the number of electrons in an atom of an element.
Element’s Symbol:An abbreviation for the element.
Elements Name
Atomic Mass/Weight:
Number of protons + neutrons.
Atomic Math: To figure out the number of Neutrons you: Subtract the ATOMIC NUMBER from the Atomic Mass (16-8=8)
