Assessment StatementsTopic 2: Atomic structure
2.1 The atom 2.1.1 State the position of protons, neutrons and electrons in the atom. 2.1.2 State the relative masses and relative charges of protons, neutrons and electrons. 2.1.3 Define the terms mass number(A), atomic number(Z) and isotopes of an element. 2.1.4 Deduce the symbol for an isotope given its mass number and atomic number 2.1.5 Calculate the number of protons, neutrons and electrons in atoms from the mass number atomic number and charge. 2.1.6 Compare the properties of the isotopes of an element. 2.1.7 Discuss the uses of radioisotopes. 2.2 The mass spectrometer 2.2.1 Describe and explain the operation of a mass spectrometer. 2.2.2 Describe how the mass spectrometer may be used to determine the relative atomic mass using the 12C scale. 2.3 Electron arrangement 2.3.1 Describe the electromagnetic spectrum. 2.3.2 Distinguish between a continuous spectrum and a line spectrum. 2.3.3 Explain how the lines in the emission spectrum of hydrogen are related to electron energy levels. 2.3.4 Deduce the electron arrangement for atoms and ions up to Z=20. |
