- Question 1written answer · 7 marks
Elements are made up of atoms. (a) Define the term 'element'. [2] The following model is given: atoms are made of three subatomic particles - neutrons, protons and electrons. A simple diagram of an oxygen atom shows protons and neutrons together in a central nucleus, with the electrons revolving around the nucleus (like planets around the sun) in shells - 2 electrons in the inner shell and 6 in…
- Question 2written answer · 16 marks
The periodic table tells us about the numbers of subatomic particles in an atom. For example, helium is shown as '4 He 2': the top number (4) is the atomic mass number - the number of protons AND neutrons - and the bottom number (2) is the atomic number - the number of protons only. (Almost all of an atom's mass is in the nucleus; the mass of the electrons is far too small to count.) (a) The ma…
- Question 3written answer · 7 marks
Sometimes the number of neutrons in an atom can vary. Atoms with the same number of protons (the same element) but a different number of neutrons are called isotopes. Oxygen has three isotopes. (a) Three oxygen isotopes are shown as A = oxygen-16, B = oxygen-17 and C = oxygen-18 (mass numbers 16, 17 and 18 written above the symbol O). Complete the atomic number in the shaded box beneath each sy…
