aluminium formula - ✔✔✔-Al3+
ammonium formula - ✔✔✔-NH4+
are electrons in the outer shell of metal atoms localized or delocalised? - ✔✔✔-delocalised
at the anode during electrolysis what do negatively charged ions lose? - ✔✔✔-electrons
at the cathode during electrolysis what do positively charged ions gain? - ✔✔✔-electrons
barium formula - ✔✔✔-Ba2+
because electrons in the outer shell of metal atoms are delocalised what are they free to do? -
✔✔✔-move through the whole structure
before the discovery of protons, neutrons and electrons how did scientists arrange elements? -
✔✔✔-in order of their atomic mass
bromide formula - ✔✔✔-Br -
calcium formula - ✔✔✔-Ca2+
,AQA GCSE Chemistry Paper 1 (Tripple) – Exam with Questions and Answers –
100% Solved
can a molten ionic compound be electrolysed? - ✔✔✔-yes because the ions can move freely
and conduct electricity
can an ionic solid be electrolysed? - ✔✔✔-no because the ions are in fixed positions and can't
move
can small molecule substances conduct electricity? - ✔✔✔-no as the molecules do not have an
overall electric charge
carbonate formula - ✔✔✔-CO3 2-
centimeters into decimeters - ✔✔✔-divide by 1000
chloride formula - ✔✔✔-Cl -
compared with alkalis what physical properties do transition elements have? - ✔✔✔-stronger
and harder but less reactive
copper (II) formula - ✔✔✔-Cu2+
during a chemical reaction: - ✔✔✔-energy must be supplied to break bonds in the reactants
and energy is released when bonds in the products are formed
end point - ✔✔✔-the point in a titration at which an indicator changes color
energy change = - ✔✔✔-energy in - energy out
, AQA GCSE Chemistry Paper 1 (Tripple) – Exam with Questions and Answers –
100% Solved
examples of acids - ✔✔✔-sulfur acid, hydraulic acid
examples of alkalines - ✔✔✔-potassium hydroxide, sodium hydroxide, calcium hydroxide and
magnesium hydroxide
examples of weak acids - ✔✔✔-ethanoic, citric, carbonic
extraction of metal: - ✔✔✔-reduction = loss of oxygen
fluoride formula - ✔✔✔-F -
for a given concentration of aqueous solution.. - ✔✔✔-the stronger an acid the lower the pH
formation of metal ore: - ✔✔✔-oxidation = gain of oxygen
formula for concentration (tiritation) - ✔✔✔-number of moles / relative formula mass
H= - ✔✔✔-acid
how are atoms in pure metals arranged? - ✔✔✔-in layers which allows metals to be bendy and
shaped
how are metals extracted from ores using carbon dioxide? - ✔✔✔-oxygen is removed from the
ore and carbon gains oxygen so it's oxidized
how are the electrons in atoms arranged? - ✔✔✔-energy levels or shells
