A Presentation that goes through the Periodic Table

1. Periodic Table

2. Group 1
•What is this also known as?
•What do Group 1 metals all have in common in terms of their
electronic structure?
•What properties must they all have as they are metals?

3. Group 1 metals and oxygen

What is the general equation for this reaction?
What is the trend in the group?

5. Are these statements true or false?
•Metals are on the right of the periodic table.
•Metal hydroxide is made when metals react with
acid.
•Group 1 metals are kept without air.
•Hydrogen is produced when group 1 metals react
with water.
•Hydrogen is tested with a glowing splint.
•Sodium is the most reactive group 1 metal.
•All group 1 metals have 6 electrons in their
outer shells.

6. Copy and complete
Group 1 metals, also known as …………………… metals, they
are highly reactive as they all have ………. electron(s) in
their outer shell. They make ………. cations when they
bond ……….. Their compounds are often ……….. solids
which dissolve in water to make ………………. solutions.
The alkali metals are not very ……………, which can be
seen by the fact that they …………… on water. They
are kept under oil as they react …………….. with ……………
and …………. in the air.

7. These are the definitions, but what are
the key words?
•This is the other name for all the group 7
elements.
•These particles are what controls the
chemistry.
•An atom that has gained electrons.
•The temperature where a chemical turns from
a solid to a liquid, or a liquid to a solid.
•When a gas turns to a solid or a solid to a gas
without turning into a liquid.

9. Group 7 names
•In the elemental form they are
known as Halogens and their name
ends in –ine.
•In compounds they change their
name to end in –ide.

11. Copy and complete
All halogens are in group ……………………… of the Periodic Table. They all have
…………… electrons in their outer shell and gain ………. to make …………… in ionic
compounds. The halogens will also bond ………… with other non-metals, by
………….. electrons. In the elemental form, they make …………… molecules,
which are bonded …………….. e.g. …………All halogens have coloured gases.
There are three trends in group 7, as you go down the group:

13. Physical Properties of Transition Metals
•Malleable
•Ductile
•Sonorous
•Lustrous
•Contain the only
magnetic
elements
(Fe, Ni and Co)
•Thermal and
electrical
conductors

14. Chemical Properties of Transition Metals
•Do they react with air? –think about copper
roofs.
•Do they react with water?
•What can the metals be used for? Think about
catalysts, also mention Fe, Cu, W.
•What are their compounds like?
•Uses of their compounds.
