Read the statement. Explain what it means about atoms in your own words.
3
What are the parts of the current model of the atom?
NUCLEUS: the dense/solid center part of an atom where most mass is found; contains the protons and the neutrons
ELECTRON CLOUD: mostly empty space surrounding nucleus where electrons are found
4
Labelling
Label the Protons, Electrons, Neutrons, Nucleus
Neutrons
Electrons
Nucleus
Protons
5
Reorder
Identify the FIRST 5 elements in the Periodic Table.
H

Multiple Choice
Identify which subatomic particle determines an atom's identity
Proton
Neutron
Electron
None of these
7
Draw
Circle the letter that represents the # of PROTONS in an element
8
Draw
Circle the letter that represents the MASS # in an element

Multiple Select
Identify which subatomic particles determines the MASS of an element. Select 2!
Proton
Neutron
Electron
None of these
