Each group will be assigned a particular group/family of elements to research.

The groups will either present their research to the rest of the class or create posts in a class padlet.  Use the guided questions given for each group of elements below. Some of the research you will need to include are listed below:

Properties – list two physical and one chemical property the elements in your group share

Record the number of valence electron/s the elements in your group have

Write down what type of ions the elements in your group form when they react with substances

List three examples of elements which belong to each group

Write down the balanced formula equations of chemical reactions involving some of these elements (groups 1 and 17 only)

Three interesting facts relevant to your group of elements

# data[].attributes.body
the atoms of nobles gases already have complete outer shells, so they have no tendency to lose, gain or share electrons. this is why the noble gases are inert

# data[].attributes.body
Fluorine, Chlorine, Bromine, Iodine, Astatine

# data[].attributes.body
-good conductors of heat and electricity
-are hard
-colourless compounds

# data[].attributes.body
-high densities
-high melting and boiling points

# data[].attributes.body
-iron
-chromium
-manganese

# data[].attributes.body
Carbon (C), Silicon (Si), Germanium (Ge), Tin (Sn), Lead (Pb)

# data[].attributes.body
- The word Halogens comes from the words hals meaning salt and gen meaning to make
- fluorine gas is deadly
- the first halogen to be recognised as an element was chlorine

# data[].attributes.body
4 valance electron

# data[].attributes.body
-1 ions

# data[].attributes.body
Transitional metals include two valence electrons (electrons in the outer shell of an atom)

# data[].attributes.body
Alkaline Earth Metals are all metals that act in a slightly less reactive way then Group 1 elements. When these metals react, alkaline earths loose 2 electrons from each atom to form ions with a charge of +2.

WHY THE NOBLE GASES ARE LESS LIKELY TO FLOAT IN THE AIR AS YOU MOE DOWN GROUP 18 

# data[].attributes.subject
WHY THE NOBLE GASES ARE LESS LIKELY TO FLOAT IN THE AIR AS YOU MOE DOWN GROUP 18 

# data[].attributes.body
The noble gases progressively denser, this makes them heavier and less likely to float in the air.

# data[].attributes.body
Found in column 1A of the periodic table.

Have one electron in their outermost layer of electrons.

Easily ionized.

Silvery, soft, and not dense.

Low melting points.

Incredibly reactive.

# data[].attributes.body
·       Shiny

·       Silvery-white.

·       Somewhat reactive metals at standard temperature and pressure.

·       Readily lose their two outermost electrons to form cations with a 2+ charge.

·       low densities.

·       low melting points.

·       low boiling points.

# data[].attributes.body
The basic earth components highly metallic and are good conductors of electricity. They have a dim white shine when newly cut yet discolour promptly in air, especially the heavier individuals from the gathering. Beryllium is adequately difficult to scratch glass, yet barium is just somewhat harder than lead.

# data[].attributes.body
wide range of properties because this group includes non-metal carbon, the metalloids silicon and germanium and the metals such as tin and lead

# data[].attributes.body
Each of two or more different physical forms in which an element can exist.

# data[].attributes.body
Alkalis react with Acids to form salt and water. This reaction is called neutralisation reaction.

Alkalis react with ammonium salts to form salt, water and ammonia gas. ...

Alkalis react with solution of metal salt to form another metal salt and hydroxide.

# data[].attributes.body
Diamond, graphite, graphene, and buckminsterfullerene

# data[].attributes.body
The alkali metals have only one valence electron in their highest-energy orbitals (ns¹).

# data[].attributes.body
All alkaline Earth metals have similar properties because they all have two valence electrons.
