1. Metals, Transition metals, Metalloids, and Non-metals
The Periodic Table
Metals, Transition metals, Metalloids, and Non-metals
Groups and Periods

2. Periods
Horizontal Rows (1-7)

3. Periods
Elements in periods are not similar. They are just in order of atomic number.
The only similarity between these elements is that they increase by one proton as you go from left to right across the period.

5. Groups
They have similar characteristics in many ways. If you know something about one element in that group, the others are close to the same.
They have the same or close to the same numbers of valence electrons. This means they bond with the same elements.

6. Parts of the Periodic Table
= Metal
= Nonmetal
= Metalloid
There are three main groups in the periodic table: 1) metals, 2) nonmetals, and 3) metalloids.

7. The Metal Group
Most of the elements in the periodic table are metals
Chemists classify an element as a metal based on physical properties such as hardness, shininess, malleability, and ductility
A malleable material is one that can be pounded into shapes
A ductile material is one that can be pulled out, or drawn into a long wire
Most metals are good conductors because they transmit heat and electricity easily
Several elements in this group can be made into magnets
Their reactivity varies as you go from left to right. The far left metals are very reactive while the far right metals are very unreactive.

8. The Transitional Metals
Transitional metals form a bridge between very reactive metals on the left side of the periodic table and the less reactive metals and elements on the right side of the periodic table
Transition metals are similar to one another
Most transition metals are hard and shiny
They are fairly stable metals and are good conductors of electricity

9. The Nonmetal Group
Nonmetals are the elements that lack most of the properties of metals
There are 17 nonmetals
Many of the nonmetals are very common elements and extremely important to all living things on earth
Many nonmetal elements are gases at room temperature and have low boiling points
The physical properties of nonmetals are opposite to those that characterize metals
They are dull, not malleable or ductile, poor conductors, and when in solid form, brittle.

10. The Metalloid Group
On the border between metals and nonmetals are seven elements called metalloids
Metalloids have some characteristics of metals and some characteristics of nonmetals
The most useful property of metalloids is their varying ability to conduct electricity
Whether or not a metalloid conducts electricity is dependent upon temperature and exposure to light
Nonmetals are also used to make semiconductors which are substances that under some conditions cannot carry electricity

11. Practice!
You have 4 cards. Each one says either metal, metalloid, nonmetal, or transitional metal
Each slide will contain a different element, you need to look and figure out which group it belongs to!
