This group's elements are soft enough to be cut with a knife, and react violently with water.
What is an Alkali metal?
100
These atomic particles are found in the nucleus of an atom.
What is the proton and neutron?
100
These are the two types of mixtures.
What is homogeneous and heterogeneous?
100
These are located on the left side of the periodic table.
What is a metal?

This atomic particle is found outside the nucleus of an atom.
What is an electron?
200
This category includes elements and compounds.
What is the two categories of pure substances?
200
These are found in a stair step pattern just to the right of the transition metals
What are the metalloids?
200
This element is in the 4th period, 18th group.
What is Krypton?
300

What is gold?
400
This group's tough, strong elements are not very reactive with other elements, but do conduct electricity and heat well.
What is a Transition metal?
400
This is equal to the number of protons or electrons in a stable atom
What is the atomic number?
400
