This scientist compared the atom to a plum pudding,or a muffin.
Who is Thomson
100
This scientist discovered neutrons in 1932.
Who is Chadwick.
100
Group 1, Period 2.
What is Li (Lithium).
100
This is the most reactive family and has 1 valence electron.
What are Alkali Metals.
100
Bombs Away! This family contains elements like Uranium and Platonium that are used in nuclear weapons.
What are the Rare Earth Metals.
200
This scientist thought of the atom as a solid ball, like a pool ball.
Who is Dalton.
200
Dalton came up with this theory, that said everything is made of atoms, and atoms of different elements are different.
What is the Atomic Theory.
200
Group 3, Period 6.
What is La (Lanthanum).
200
This is the largest family, and contains elements like Copper and Gold.
What are the Transition Metals.
200
As you gaze at a beautiful sunset, you think about these elements that are present in the atmosphere to make all those colors.
What are the Nobel Gases.
300
In this atomic model, we think of the atom as a negativly charged "cloud" of electrons around the nucleus.
What is the modern model.
300
This scientist said that electrons move around the nucleus in shells, much like planets around the sun.
Who is Bohr.
300
DAYLY DOUBLE!!!!!!
Group 14, Period 3.
What is Si (Silicon).
300
This family is very stable with 8 valence electrons.
What are the Nobel Gases.
300
WaBoom! You swing a sledgehammer thats head is made of Iron, a memeber of this Family.
What are the Transition Metals.
400
DAYLY DOUBLE!!!!!!
This scientist came up with the "planitary model" of the atom.
Who is Bohr.
400
Thomson discovered this subatomic particle (think electricicty).
What is the electron.
400
Period 7, Group 4.
What is Rf (Rutherfordium).
400
Iodine, Chlorine and Florine are dangerous elements that come from this family.
What are the Halogens.
400
BRRRZAPP! Magnesium is often used in welding rods, and produces a bright light when it reacts. It is a member of this family.
What are the Alkaline Earth Metals.
500
This scientist thought of the atom like a peach with a solid pit (the nucleus) and electrons randomly scattered around.
Who is Rutherford.
500
This scientist discovered protons and the nucleus. He did this using the Gold Foil Experement.
Who is Rutherford.
500
Period 3, Group 17.
What is Cl (Chlorine).
500
These elements form a "zig-zag" line that divide the metals from the nonmetals. They have properties of both.
What are the metaloids.
500
Ewwwwww. You notice your pool is looking scummy, so you put in Chlorine to clean it out. Chlorine is a member of this family that has 7 valence electrons.
