Halogens

  • Similar properties
  • Low melting point
  • Reactant, as you go down reactivity decreases
33
Q

Halogen elements

A 
Fluorine 
Chlorine
Bromine
Iodine 
Astatine
34
Q

Noble gases

A
  • gas at room temperature
  • odourless and colourless
  • unreactive
35
Q

Noble gas elements

A 
Helium 
Neon
Argón
Krypton
Xenon 
Randon
36
Q

Alkali metals

A
  • reactive
  • soft
  • alkali
  • more reactive as you go down
37
Q

Atoms

A

Smallest particles

38
Q

Molecules

A

Two or more atoms chemicaly joined (bonded) together

39
Q

Elements

A

Substances when all the atoms are the same type. Can be alone or joined as molecules

40
Q

Compounds

A

Molecules made up of different types of atoms chemicaly bonded together

41
Q

Mixtures

A

Different elements or compounds mixed together but NOT CHEMICALLY joined

42
Q

Uses of Noble Gases

A
  • Helium=Used for balloons
  • Neon=Used for signs
  • Argon=Unreactive atmosphere
  • Krypton=Camera flashes
  • Xenon=Car/fluorescent lights
  • Radon=Quimioterapy
43
Q

Reactant

A

React together

44
Q

Products

A

The things that are made

45
Q

In all chemical reactions…

A

The atoms in the reactants are rearranged to form products.The products are always different from the reactants

46
Q

How do we name the compound of a metal reacting with a non metal

A

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
Q

When they give you a compound to tell the element how do we answer them

A

The metal stays the same and the nonmetal changes from its changed ending to its normal name
E.g.
Chloride - Chlorine

48
Q

When a nonmetal ends with (ate) what does it contain

A

Oxygen

49
Q

What does H2O stand for

A

2 hydrogen atoms and one oxygen atom

50
Q

How do we write chemical formula

A

The numbers have to be small at the bottom

51
Q

Test for hydrogen gas

A

A splint goes out with a squeaky pop

52
Q

Test for oxygen

A

A glowing flint relights

53
Q

Test for carbon dioxide

A

Limewater turns milky/cloudy

54
Q

How are elements arranged in the periodic table

A

In groups with similar properties

55
Q

Groups

A

Vertical columns

56
Q

Periods

A

Horizontal colums

57
Q

Halogen appearance

A

60
Q

Group 8

A

Noble gases

61
Q

Nobel gases are?

A

62
Q

Why is helium used for balloons

A

Because helium is lighter than air or less dense

63
Q

Transition metals have properties of?

A

Normal metals: hard, shiny, good conductors

64
Q

With what do alkali metals react?

A

With water, get more reactive when we go down

65
Q

Alkali metals properties

A

Soft and dull

66
Q

Lithium + water

A

Fizzing

67
Q

Sodium +water

A

Fizzing and become a sphere shape

68
Q

Potassium + water

A

Purple flame

69
Q

The halogens are less reactive

A

As we go down the group

70
Q

F

A

Very pale yellow gas

71
Q

Cl

A

Pale green gas

72
Q

Be

A
