A type of element with differing numbers of neutrons
33
What is ionic bonding?
Between 2 atoms, 1 atom has lost an electron and the other has gained one
34
What is an atomic number?
The sum of electrons and protons (not neutrons) combined in an atom.
(Always the same amount of each)
35
What is the atomic MASS number?
Number of protons and neutrons (electrons are light so don't count)
R.E.M. MASS+Neutrons
36
Letter "P" after a guide number means what?
May undergo violent polymerisation if heated or contaminated
37
Information resources are?
```
MSDS
Chemdata
ERG
WISER
Internet
Weathermet/Chemmet
```
38
Need to knows on vapours are?
```
How much vapour?
Heavier than air?
Flammable?
Water reactive?
Will water curtain reduce the vapours?
```
39
Boiling point is?
Temperature at which a material becomes a Gas or vapour
40
Vapour pressure is?
Measure of how volatile a substance is
Atmospheric pressure is 100kpa
Water 3kpa
Petrol 30-65kpa
Diesel 0.6kpa
41
Vapour Density is?
Relative density of a vapour compared to Air
Air =1
Heavier than 1 =low lying vapour
Less than 1 = high lying vapour
42
LEL is?
Lowest % of a substance in air which can be ignited
43
What causes vapour pressure to rise?
Temperature / heat
44

Guide 114
49
If an "X" appears before a Hazard identification number (e.g X30 or X33 as an intensification of that hazard) on the top half of an orange panel, what does it mean?
X = react dangerously with water
(X=No water)
Zero after number is no intensification (e.g. What would be X3 or 3 would be 30 or X30)
50
