Columns on the Periodic Chart are referred to as _________ of elements.
-Families
Families of Elements are similar in at least what three ways?
-Charge, Electron configuration, Electron dot diagram, also they have similar properties
What are the 3 properties of the Alkali family?
-Soft, Shiny, Very reactive
Compare the Alkali's to the Alkali Earth metals. What is the difference in their properties? Why is there a difference?
-They have the same properties but not as strong. It is harder to drop two electrons.
List four of the transition metals properties.
-Shiny, hard, dense, bends and holds its shape,
conducts electricity, conducts heat, corrodes
The only "orphan" element on the chart ____________ .
-Hydrogen
If both B^5 and Al^13 are s^2p^1,s why is Boron a nonmetallic metalloid and Al a metallic metalloid?
-Boron has fewer total electrons so it is less inclined to give them away.
The Carbon family elements radically change in their individuals properties. How do they change from C to Pb?
-It goes from non-metal to metalloid to metals
What factor cause these changes in the Carbon family? Explain.
-Size of the atoms
In summary, what two major factors strongly affects the properties of any single element or any family of elements on the chart?
-Structure, Size
Carbon’s 2s2 2p2 orbital rearrange to bond in four different directions, what is the name of this shape? Sketch it. - Tetrahedral

Carbon forms long chains with itself, this is referred to as __________. In industry, this process is called___________. Examples of these substances would be: ___________and___________.
-Catenation, Polymerization, Plastic, Nylons
Carbon is very user-friendly and therefore predominantly found in the chemistry of living things, this chemistry is called__________ chemistry.
-Organic
Halogen means "salt-forming" and the halogen family bonds easily to what other family on the Periodic
Chart?
-Alkali
Using electron dot diagrams, show what this bonding might look like for one element from each of these families:

Within the Halogen Family, two elements are solids, one a liquid, and two gases.
- I-solid, Br-liquid, F, Cl-gases
How does chlorine kill bacteria or microorganisms in a swimming pool?
-It breaks the carbon chain and water pours inside the organism, drowning it.
What substances do you NEVER mix with bleach?
-Ammonia, and Acid
The Noble Gases do not react because?
-They have an octet
The element that does not really have an octet is_________. Why does it then act like a Noble Gas?
-Helium, Its valence shell is full.
Why is Silicon, Si, dangerous to some carbon based life form units if it is the element that is most like carbon?
-Its slightly more metallic.
Elements that bond to themselves in pairs (two atoms of the same element) are called _________ molecules.
-Diatomic
Nitrogen, Oxygen, and Fluorine each form these paired elements above. Show how each of these elements bond, using their electron dot diagram:

Oxygen, O2, has an allotrope up in the atmosphere called_________. What is its formula.
-Ozone, O3
How does this compound Protect our planet from too much UV
light?
-Absorbs 30% of UV light because it vibrates at the same rate of UV light.
What carbon compound destroys this molecule of oxygen and in what products is it found?
- Cfc - Chlorofluorocarbon
Why might Al be less metallic than Na or Mg?
-Harder to give away three electrons than two.
In general, metals tend to want to__________ their electrons and nonmetals tend to want to __________ their electrons.
-Give away, Keep
