0 1 1 The plum pudding model suggested that: Tick (✓) one box:
o Atoms are indivisible spheres.
o Atoms consist of electrons embedded in a sphere of positive
charge.
o Atoms contain a dense nucleus surrounded by electrons.
o Atoms contain protons and neutrons in the nucleus.
(1 mark)
0 1 2 Fill in the blanks. The nuclear model of the atom was developed
after the alpha particle scattering experiment. In this experiment:
o Most alpha particles passed through the gold foil,
showing that atoms are mostly ________.
o A few particles were deflected, suggesting that the
________ is small and positively charged.
(2 marks)
0 1 3 An element 𝑋 has two isotopes with the following data:
Isotope Mass Number Percentage Abundance
𝑋 69 69 60%
𝑋 71 71 40%
Calculate the relative atomic mass (𝐴𝑟 ) of element 𝑋. Show your working
and give your answer to 1 decimal place.
