Resource summary

Chemistry C1 (Edexcel) Core
1 Atoms
1.1 Electrons
1.1.1 Move Around the Nucleus
1.1.2 Negative Charge -1
1.1.3 2 Atoms in the first Shell 8 in the rest E.G oxygen (8 Electrons) 2 on the inner 6 on the next
1.2 Nucleus
1.2.1 Centre of an Atom
1.2.2 Contains Protons and Neutrons
1.2.3 Positive Charge +1 Negative Charge 0
1.2.4 Almost whole mass of atom is concentrated here
1.3 Protons
1.3.1 Equal but opposite charges
1.3.2 Same number of electrons and protons in an atom
2 Elements
2.1 Only have 1 type of atom.
2.2 Each element has a different number of protons
3 Mixtures and Compunds
3.1 Mixtures are easily seperated
3.2 Compounds are chemically bonded
3.3 properties of compounds are different to original element
3.4 Naming Compounds 1) when two different elements combine, the compounds name is something-IDE 2) When three or more elements combine, and one of them is oxygen the compounds name is something ATE
4 Chemical Reactions
4.1 Exothermic Reactions
4.1.1 Exothermic reactions give out heat to surroundings and are shown by a rise in temperature
4.2 Endothermic Reactions
4.2.1 Endothermic Reactions take in heat from the surrounding, and are shown by a fall in temperatre
5 Periodic Table
5.1 Elements are put in order of increasing atomic number
5.2 Dimitri Mendeleev made the table of elements 1869
5.2.1 Gaps in his table predicted properties of undiscovered elements
5.3 Periods
5.3.1 Rows are called Periods
5.3.2 Properties of elements change as you go along a period
5.4 Groups
5.4.1 columns are called groups
5.4.2 properties of elements have similar properties because they have the same number of electrons in the outer shell
5.4.3 properties of elements gradually change as you go down a group.
6 Common Substances and ions
6.1 Water (H2O)
6.1.1 Carbon Dioxide (CO2) Carbon Monoxide (CO) Sodium Hydroxide (naoh) Ammonie (nh3) Methane (ch4) Sodium Hydroxide Carbonate (nahco3)
6.2 Positive Ions +1
6.2.1 Hydrogen (H)
6.2.2 Silver (AG)
6.2.3 all the first group of metals
6.3 Positive Ions +2
6.3.1 Iron (II) (FE)
6.3.2 Copper (II) (Cu)
6.3.3 Zinc (Zn)
6.3.4 All the second group of metals
6.4 Positive ions +3
6.4.1 Aluminium (AL)
6.4.2 Ion (III)
6.5 Negative Ions -2
6.5.1 Oxide (O)
6.5.2 Sulphide (S)
6.5.3 Carbonate (CO3)
6.5.4 Sulphate (SO4)
6.6 Negative -1
6.6.1 Hydroxide (OH)
6.6.2 Nitrate (NO3)
6.6.3 All of the seventh group of metals
7 Alkali Metals (Group 1)
7.1 They have one electron on the outer shell and want to get rid of it so they are very active
7.2 Elements further down the group are more reactive because the extra electron if further from the nucleus.
7.3 Elements in group 1 are more reactive as the atomic number increases.
7.4 Alkali Metal + water -----> Metal Hydroxide + Hydrogen
8 The Halogens (Group 7)
8.1 Halogens are used in toothpaste and non-stick coasting on frying pans
8.2 On their own they are poisonous
8.3 Chlorine is used to kill bacteria and is used in bleach and swimming pools.
8.4 Iodine is used as an antiseptic
8.5 Aas the atomic number increases the elements get darker and have a higher boiling point
8.6 the higher up group 7 the element is, the more reactive it is.
8.7 Halogens move around in pairs, they are diatomic
8.8 Metals + Halogen = Salt (Metal Halide)
8.8.1 E.G Aluminium + Chlorine = Aluminium ChlorIDE
8.9 Fluorine (F) , Pale Yellow Gas.
8.9.1 Chlorine (CL), Pale Green Gas Bromine (BR), Dark Red Liquid Iodine (I) Purple Black Liquid Astatine (AT) Grey-Black Solid
9 Noble Gases (Group O)
9.1 Colourless at room temperature.
9.2 Inert full outer shell so they don't react
9.3 Neon is used in electric discharge tubes (red Light)
9.4 Helium neon and argon are used in lasers
9.5 Helium is used in airships and party balloons
9.6 Argon is used in Filament laps (Light Bulbs)
10 Precipitates
10.1 Cobalt - Blue (turns grey when left standing.
10.2 Copper - Pale Blue
10.3 Iron (II) Dark green (Turns orange brown when left standing)
10.4 Iron (III) - Orange Brown
10.5 Manganese - Pale Brown
10.6 Nickel - Green
10.7 Zinc- White
11 Flame Test Colours
11.1 Lithium RED
11.3 Potassium LILAC
11.4 Calcium BRICK RED
11.5 Barium PALE GREEN
11.6 Copper GREEN BLUE
12 Acids and Bases.
12.1 Alkalis are Soluble
12.2 Citric Acid - Food Additive to add sour taste to foods and soft drinks
12.3 Ethanoic Acid - Acid in Vinegar. Used in bottles and photographic film and wood glue. diluted ethanoic acid is used as a descaling agent for kettle.
12.4 Hydrochloric acid - Plastics. used to process steel. Dilute solutions used for cleaning, stomach acid
12.5 Phosphoric Acid - production of petrol, nylon and detergents
12.6 Ammonia Fertilizers - used in manufacturing of nitric acid and sodium carbonate. Dilute Ammonia used for cleaning.
12.7 Sodium Hydroxide - Caustic Soda. Used to make Bleach and other cleaning products E.G drain unblocker. used in soap, paper and textile manufacture
