1. Metals, Nonmetals, Metalloids

2. The elements of the periodic table can be divided into three main categories: Metals, Non-Metals, and Metalloids.

3. Properties of Metals
Metals are good conductors of heat and electricity.
Metals are shiny.
Metals are ductile (can be stretched into thin wires).
Metals are malleable (can be pounded into thin sheets).
A chemical property of metal is its reaction with water which results in corrosion.

4. Properties of Non-Metals
Non-metals are poor conductors of heat and electricity.
Non-metals are not ductile or malleable.
Solid non-metals are brittle and break easily.
They are dull.
Many non-metals are gases.
Sulfur

5. Properties of Metalloids
Metalloids (metal-like) have properties of both metals and non-metals.
They are solids that can be shiny or dull.
They conduct heat and electricity better than non-metals but not as well as metals.
They are ductile and malleable.
Silicon

[MC Any]
[MC All]

12. 8. The nucleus of an atom
A unique number that represents the number of protons in an atom.
Is the dense, positively charged mass located in the center of an atom.
A particle smaller than an atom (e.g. neutron)
A visual model of the most likely locations for the electrons in an atom.

[MC All]

13. 9. If you are given the mass number and the atomic number for an atom, how would you determine the number of neutrons?
Subtract the atomic number from the mass number.
Determine the number of electrons because that will tell you the number of neutrons.
Determine what period the element is in.
Count the number of valence electrons.
