Elements & Atoms Matter Refresher Matter is anything that takes up space and has mass. All matter is made of atoms Atoms are the building blocks of matter, sort of how bricks are the building blocks of houses. Created by G.Baker www.thesciencequeen.net The Atom An atom has three parts:...
Matter Atoms and Elements I can recognize that there are more than 100 different elements that make up all living and nonliving things. I can identify atoms as the simplest form of each element and the building blocks of all matter. Brainpop Matter: Atoms and Elements 6.P.2.1 Recognize that...

(3) Atoms of different elements are different. (4) Atoms of different elements join together to make compounds. In the late 1800’s, J. J. Thomson discovered that atoms were made of smaller particles. He discovered the electron and devised the “chocolate-chip cookie” model of the atom....

Nuclei are composed of particles called protons and neutrons, which are themselves made up of even smaller particles called quarks. Quarks are believed to be fundamental, meaning that they cannot be broken up into smaller particles. Chemical Elements Isotopes Ions Isotopic Masses Atomic Mass The ...
