Elements in the periodic table
118
Halogens
Halogens
- Similar properties
- Low melting point
- Reactant, as you go down reactivity decreases
Halogen elements
Fluorine Chlorine Bromine Iodine Astatine
Noble gases
- gas at room temperature
- odourless and colourless
- unreactive
Noble gas elements
Helium Neon Argón Krypton Xenon Randon
Alkali metals
- reactive
- soft
- alkali
- more reactive as you go down
Atoms
Smallest particles
Molecules
Two or more atoms chemicaly joined (bonded) together
Elements
Substances when all the atoms are the same type. Can be alone or joined as molecules
Compounds
Molecules made up of different types of atoms chemicaly bonded together
Mixtures
Different elements or compounds mixed together but NOT CHEMICALLY joined
Uses of Noble Gases
- Helium=Used for balloons
- Neon=Used for signs
- Argon=Unreactive atmosphere
- Krypton=Camera flashes
- Xenon=Car/fluorescent lights
- Radon=Quimioterapy
Reactant
React together
Products
The things that are made
In all chemical reactions…
The atoms in the reactants are rearranged to form products.The products are always different from the reactants
How do we name the compound of a metal reacting with a non metal
The name of the metal stays the same
The name of the nonmetal is added to the end, but the ending of the name changes to -ide
When they give you a compound to tell the element how do we answer them
The metal stays the same and the nonmetal changes from its changed ending to its normal name
E.g.
Chloride - Chlorine
When a nonmetal ends with (ate) what does it contain
Oxygen
What does H2O stand for
2 hydrogen atoms and one oxygen atom
How do we write chemical formula
The numbers have to be small at the bottom
Test for hydrogen gas
A splint goes out with a squeaky pop
Test for oxygen
A glowing flint relights
Test for carbon dioxide
Limewater turns milky/cloudy
How are elements arranged in the periodic table
In groups with similar properties
Groups
Vertical columns
Periods

Halogen appearance
Fluorine:pale yellow Chlorine:green Bromine:brown/orange Iodine:black Astatine:black
Group 1
Alkali metals
Middle bit
Transition metals
Group 8
Noble gases
Nobel gases are?
Very unreactive
Why is helium used for balloons
Because helium is lighter than air or less dense
Transition metals have properties of?
Normal metals: hard, shiny, good conductors
With what do alkali metals react?
With water, get more reactive when we go down
Alkali metals properties
Soft and dull
Lithium + water
Fizzing
Sodium +water
Fizzing and become a sphere shape
Potassium + water
Purple flame
The halogens are less reactive
As we go down the group
F
Very pale yellow gas
Cl
Pale green gas
Be
Orange liquid
I
Grey solid
