Properties of Groups on the PeriodicTable


2/22

What is similar about elements in aGroup (column) on the periodic

table?

1. Elements in a Group (column)

have similar physical andchemical properties.

2. This means elements in aGroup are more like eachother than any

other

element!


3/22

What are 3 examples of

Physical Properties?1.How an element looks or feels( soft? hard? shiny? dull? malleable? brittle? ductile? )

2.Atomic structure(how many protons? neutrons? electrons?)

3.Conductivity(good conductor of heat? of electricity?)


4/22

What is 1 example of a

chemical property?

The reactivity of an element when itcombines with other elements. It has todo with the valence electrons.

(does it explode? does it make a new chemical? does itproduce light? maybe it does nothing!)


5/22

What are the properties ofAlkali Metals?

Group 1Alkali Metals


6/22

1. Soft2. Extremely reactive3. 1 valence electron

Sodium

Group 1Alkali Metals

What are the properties ofAlkali Metals?


7/22

Alkali Metals

Lithium

Sodium

Potassium Rubidium

Cesium

Francium


8/22

Group 2Alkaline Earth Metals

What are the properties of

Alkaline Earth Metals?


9/22

1. Soft

(but not as soft as group 1).

2. Very reactive(but not as reactive as group 1).

3. 2 valence electrons

Group 2Alkaline Earth Metals

Calcium Calciumin water

What are the properties of

Alkaline Earth Metals?


10/22

Alkaline Earth Metals

Beryllium

Magnesium

Calcium Strontium

Barium

Radium


11/22

Groups 3-12Transition Metals

What are the properties of the

Transition Metals?

Lanthanide and

Actinide Series


12/22


1.Hardest metals(high melting and boiling points)

2.Best conductors out of all

metals

3. Can react, but usually makemixtures like alloys


Transition Metals?


13/22


Pennies are analloy of 98% zincand2% copper.Zinc and copperare both transition

metals!


Transition Metals?


14/22

Transition Metals

Many!


15/22

Boron, Carbon, Nitrogen, & Oxygen Groups

Nothing specialabout these groups,they contain all typesof elements. Group 13 has 3valence electrons,Group 14 has 4,Group 15 has 5, etc.


Group 13-16?


16/22

Groups 13 - 16


17/22

Group 17: Halogens


Halogens?


18/22

Group 17: Halogens1. 7 valence electrons

2. Extremely reactive

3. Gain Electrons


Halogens?


19/22

Group 18: Noble Gases


Noble Gases?


20/22

Group 18: Noble Gases

1. Colorless and odorless2. 8 valence electrons theyhave a full outer orbital, thisis why they dont react

3. Inert gases meaning theyare unreactive with otherelements!


Noble Gases?


21/22

Label the Groups


22/22

Output:

Conclusion: Write 5 sentencesdescribing the properties of the groupsof the periodic table. Include the alkali

metals, alkaline earth metals, transitionmetals, halogens, and inert/noble gases.
