Label the parts of the atom:
Match the particle to its description
+1 charge, located in the nucleus, mass of 1 AMU
proton
-1 charge, located in the energy rings, mass of 0 AMU
electron
neutral charge, located in the nucleus, mass of 1 AMU
neutron
positive charge, all of the mass is here, contains 2 different particles
nucleus
negatively charged particles live here, is mostly empty space
atomic orbitals
Match the properties to the correct category:
vertical columns
elements in the same one have similar properties
elements in the same one have the same number of valence electrons
horizontal rows
elements in the same one have the same number of energy levels
there are 7 of these on the periodic table
there are 18 of these on the periodic table

Label the different models of the atom with the scientist that developed it:
Match the scientist to their atomic model:
Dalton
Thomson
Rutherford
Bohr
Schrodinger (quantum model)
Match the scientist to their believed description of the atom:
Believed that atoms are tiny, hard spheres that cannot be split up
Dalton
Believed that electrons were distributed throughout a positively charged sphere
Thomson
Discovered that most of the atom's mass is in the nucleus
Rutherford
Discovered that protons AND neutrons are in the nucleus & believed that electrons orbited the nucleus in specific orbitals
Bohr
Discovered that we cannot predict where an electron will be at an given time but that they move as "clouds".
Schrodinger
(a) weakness was that he failed to recognize the (b) . Instead, he believed that all matter was composed of extremely small, solid, and indivisible particles called (c) .
According to (a) , an atom is made of mostly (b) . His gold foil experiment provided evidence that there is a dense, (c) charged (d) at the center of an atom.
(a) experimented with (b) , which were once used in old TV's. He determined that atoms contained small (c) charged particles called electrons. We call this the (d) .
(a) suggested that electrons existed in specific orbitals, like planets orbiting around the sun. We called this the (b) model. He determined that the (c) contains all of the mass of an atom but takes up a very small portion of the actual volume, suggesting that the nucleus is (d)
(a) suggested that an atom contains a central nucleus that contains (b) , which identify the element, and (c) that are neutral. He said that the (d) are more like clouds that contain (e) .
Label the atom:
Match the description to the particle:
Mass = 1 AMU
location = nucleus

location = nucleus
charge = 0
neutron
Mass = 0 AMU
location = rings
charge = -1
electrons
This particle IDENTIFIES the atom.
