ATOM
Fold down front page (Atom Page) of booklet.
On back of (Atom Page) write following items:
• Atoms are made of a nucleus and an electron cloud.
• Nucleus – center of atom, location of protons & neutrons, contains most of atom’s mass.
• Electron cloud – location of electrons in electron orbitals ( electron paths).
On the “Neutron” page of the booklet, write the following items.
• Located in the atomic nucleus
• Neutral, no charged particles
• Mass of each particle = 1
• Atomic Mass of element – no. of protons = no. of neutrons
On the “Protons” page of the booklet, write the following items.
• Located in the atomic nucleus
• Positively (+) charged particles
• Mass of each particle = 1
• Atomic no. of element = number of protons
On the “Electrons” page of the booklet, write the following items.
• Located in the electron cloud
• Negatively (-) charged particles
• Mass of each particle = 0
• Number of electrons = number of protons
• Symbol: e-
Color the Following:
“Electron” tab & (e-) on Atom model: YELLOW
“Proton” tab & protons on model: RED
“Neutron” tab & neutrons on model: BLUE
Label Charges on Atom Model
• Beside each electron: write, “(-) charge”
• Beside each proton: write, “(+) charge”
• Beside each neutron: write, “neutral”
