THE PERIODIC TABLE

Matter is made up of just over 100 elements. Element- a substance that cannot be broken down into any other substance by HEAT, LIGHT, or ELECTRICITY. (The building blocks of Matter)

Ex: Neon, Hydrogen, Gold, Copper, Silver, Zinc, Xenon,

Atoms Materials

P- Seeds, Beans, Clay---*heavy N- rice, cereal E- Buttons, Beads, pipe cleaners, pom poms

Anything bendy you can use to be the color shade to put neutrons and protons onto not just pipe cleaners. Only choose element from rows 1, 2, 3, 4 ,5, 6

Atoms make up matter. If 4 billion of them were lined up next to each other they would measure to only about 1 millimeter long. Dmitri Menderleer classified the elements on the Periodic Table. he laid them out least mass to greatest mass which put them from lightest to the heaviest. An Atom is the smallest particle of an element that has the properties of the element.

Nucleus- the center of the atom which contains protons and neutrons.

Proton- a subatomic particle in an atom with a __positive__ electrical charge.

Neutron- a subatomic with no charge.

Electron- a subatomic particle with a negative charge.

The number of proton's equal the number of electron's. element's or (atom's) can have a different number of neutron's.

Atomic number- the number of proton's (equal to the same number of electron's).

Atomic mass or weight- proton's and neutron's.

__Finding neutron's__ Rounding to whole number's AL=27 subtract proton's 27-13=14 neutron's.
