31
Elements in the periodic table
118
32
Halogens
Halogens
- Similar properties
- Low melting point
- Reactant, as you go down reactivity decreases
33
Halogen elements
```
Fluorine
Chlorine
Bromine
Iodine
Astatine
```
34
Noble gases
- gas at room temperature
- odourless and colourless
- unreactive
35
Noble gas elements
```
Helium
Neon
Argón
Krypton
Xenon
Randon
```
36
Alkali metals
- reactive
- soft
- alkali
- more reactive as you go down
37
Atoms
Smallest particles
38
Molecules
Two or more atoms chemicaly joined (bonded) together
39
Elements
Substances when all the atoms are the same type. Can be alone or joined as molecules
40
Compounds
Molecules made up of different types of atoms chemicaly bonded together
41
Mixtures
Different elements or compounds mixed together but NOT CHEMICALLY joined
42
Uses of Noble Gases
- Helium=Used for balloons
- Neon=Used for signs
- Argon=Unreactive atmosphere
- Krypton=Camera flashes
- Xenon=Car/fluorescent lights
- Radon=Quimioterapy
43
Reactant
React together
44
Products
The things that are made
45
In all chemical reactions...
The atoms in the reactants are rearranged to form products.The products are always different from the reactants
46
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
47
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
48
When a nonmetal ends with (ate) what does it contain
Oxygen
49
What does H2O stand for
2 hydrogen atoms and one oxygen atom
50
How do we write chemical formula
The numbers have to be small at the bottom
51
Test for hydrogen gas
A splint goes out with a squeaky pop
52
Test for oxygen
A glowing flint relights
53
Test for carbon dioxide
Limewater turns milky/cloudy
54
How are elements arranged in the periodic table
In groups with similar properties
55
Groups
Vertical columns
56
Periods
Horizontal colums
57
Halogen appearance
```
Fluorine:pale yellow
Chlorine:green
Bromine:brown/orange
Iodine:black
Astatine:black
```
58
Group 1
Alkali metals
59
Middle bit
Transition metals
60
Group 8
Noble gases
61
Nobel gases are?
Very unreactive
62
Why is helium used for balloons
Because helium is lighter than air or less dense
63
Transition metals have properties of?
Normal metals: hard, shiny, good conductors
64
With what do alkali metals react?
With water, get more reactive when we go down
65
Alkali metals properties
Soft and dull
66
Lithium + water
Fizzing
67
Sodium +water
Fizzing and become a sphere shape
68
Potassium + water
Purple flame
69
The halogens are less reactive
As we go down the group
70
F
Very pale yellow gas
71
Cl
Pale green gas
72
Be
Orange liquid
73
I
Grey solid
