CHEMISTRY - PAPER 1
1. CORRECT ANSWER -C1 Atomic Structure
2. Atoms are the particles that make up everything - CORRECT ANSWER -What are
atoms?
3. An element is a substance in which all the atoms are the same - CORRECT
ANSWER -What is an element?
4. Elements are shown in the Periodic table - CORRECT ANSWER -Where are
elements shown?
5. There are around 118 elements - CORRECT ANSWER -How many elements are
there?
6. A compound is a substance that contain two or more elements chemically combined
- CORRECT ANSWER -What is a compound?
7. The properties of compounds are usually different to the elements that they are
made from - CORRECT ANSWER -Describe the properties of compounds
8. A mixture is a substance with different elements or compounds not chemically
combined - CORRECT ANSWER -What is a mixture?
,9. An example of a mixture is sand and water as they are not chemically combined and
can be separated by physical means - CORRECT ANSWER -Give an example of a
mixture
10. A molecule is a substance that has any elements chemically joined - CORRECT
ANSWER -What is a molecule?
11. A chemical formula tells the elements in a molecule and the number of atoms of
each element - CORRECT ANSWER -What does a chemical formula tell you
about a molecule?
12. Each element symbol starts with a capital letter, if there is a second letter it is in
lower case - CORRECT ANSWER -How is a chemical formula presented?
13. CORRECT ANSWER -Give an example of a chemical formula
14. State symbols show the physical state of the substance solid (s), liquid (l), gas (g), or
dissolved in water (aq) - CORRECT ANSWER -What are state symbols?
15. -Strong
16. -Good conductors of heat and electricity
17. -High melting and boiling points - CORRECT ANSWER -Name three properties of
Metals
18. -Weak
19. -Bad conductors of heat and electricity
20. -Low melting and boiling points - CORRECT ANSWER -Name three properties of
Non-Metals
,21. Four different ways of separating mixtures are filtration, crystallisation, distillation or
chromatography - CORRECT ANSWER -State the four different ways of
separating mixtures
22. Pour your mixture onto the filter paper, the liquid simply passes through the filter
paper into the flask. The insoluble solid cannot pass through and so it stays on the
paper - CORRECT ANSWER -Describe the process of filtration
23. Use the method of filtration to filter off any excess soluble solid. Evaporate the
mixture then transfer the hot mixture onto a dish. Crystals are formed when the
mixture has cooled - CORRECT ANSWER -Describe the process of crystallisation
24. First we evaporate the mixture by heating it, the dissolved solid then vaporises.
These vapours condense in the condenser, the dissolved solid then flows into the
beaker and liquid stays in the flask - CORRECT ANSWER -Describe the process of
simple distillation
25. Take a strip of filter paper and draw a line on the bottom of the paper. Put a small
drop of ink on the line, take a jar full of water up to the line and put the filter paper
in. As the water moves up we see different colours on the paper these are the dyes in
the ink - CORRECT ANSWER -Describe the process of chromatography
26. Early ideas of the structure of atoms stated that they are tiny spheres that cannot be
divided - CORRECT ANSWER -What were the early ideas of the structure of
atoms?
27. The plum pudding model is what scientists suggested is the structure of atoms is
after the discovery of the electron - CORRECT ANSWER -What is the plum
pudding model?
, 28. The plum pudding model suggested that an atom is a ball of positive charge with
negative electrons in embedded in it - CORRECT ANSWER -Describe the plum
pudding model
29. Rutherford took a piece of gold foil, he then fired tiny positive alpha particles at the
gold foil - CORRECT ANSWER -Describe how Rutherford carried out the gold foil
experiment
30. Rutherford observed that most of the particles when straight through the gold foil
and sometimes the alpha particles bounce back of the gold foil - CORRECT
ANSWER -What did Rutherford observe in the experiment?
31. Rutherford discovered that atoms are mainly empty space as most of the alpha
particles went straight through the gold atoms and that the nucleus of the atom is
very small as only a small number of alpha particles bounce back - CORRECT
ANSWER -What did Rutherford discover from these observations?
32. The nuclear model states that most of an atom is empty space, in the centre is the
nucleus which contains protons and neutrons around the edge we find electrons -
CORRECT ANSWER -Describe the structure of the nuclear model
33. CORRECT ANSWER -What is the Relative mass and the relative charge of
protons, neutrons and electrons?
34. Because atoms have have no overall charge - CORRECT ANSWER -Why do atoms
have the same number of protons as electrons?
35. An ion is a charged particle, it is possible to get positive or negative ions -
CORRECT ANSWER -What is an Ion?
