QUESTION 1 The tаble gives sоme infоrmаtiоn аbout three subatomic particles. a(i) Complete the table by giving the missing information (nr. 1.1 - 1.3). Subatomic particle Relative mass Relative charge electron 0.0005 1.1 proton 1.2 +1 neutron 1 1.3 (3) a(ii) Give the name of the part of the atom containing protons and neutrons. (1) b The table below shows the numbers of protons, neutrons and electrons in the species U, V, W, X, Y and Z. Species Number of protons Number of neutrons Number of electrons U 8 10 8 V 9 10 10 W 11 12 10 X 11 12 11 Y 12 12 12 Z 12 13 12 Use the information in the table to answer these questions. Each species may be used once, more than once or not at all. b(i) Give the letter of the species that has six electrons in its outer shell. (1) b(ii) Give the mass number of Z. (1) b(iii) Give the letter of the species that is a positive ion. (1) b(iv) Give the letters of the two species that are isotopes of the same element. (1) c A sample of neon contains two isotopes, 20Ne and 22Ne. The relative abundances of the two isotopes in the sample are: 20Ne = 89.2% 22Ne = 10.80% Calculate the relative atomic mass of this sample of neon. Give your answer to one decimal place. (3) [11]
