C01 Atomic Structure and the Periodic Table
What’s on the Specification
C1.1 Describe the structure of the atom as a central nucleus (containing protons and neutrons) surrounded by electrons moving in shells/energy levels.
C1.2 Know the relative masses and charges of protons, neutrons and electrons, and recognise that most of the mass of an atom is in the nucleus. nucleus.
C1.3 Know and be able to use the terms atomic number and mass number, together with standard notation (e.g. ), and so be able to calculate the number ot protons, neutrons and electrons in any atom or ion.
C1.4 Use the atomic number to write the electron configurations of the first 20 elements in the Periodic Table (H to Ca) in comma-separated format (e.g. 2,8,8,1 for a potassium atom).
C1.5 Know the definition of isotopes as atoms of an element with the same number of protons but different numbers of neutrons (so having different mass numbers). Use data, including that from a mass spectrometer, to identify the number and abundances of different isotopes of elements.
C1.6 Know and use the concept of relative atomic mass, Ar, including calculating values from given data.
C2.1 Know that Periods are horizontal rows and Groups are vertical columns.
C2.2 Know that the elements are arranged in the order of increasing atomic number.
C2.3 Recall the position of metals and non-metals in the Periodic Table: alkali metals (Group 1), alkaline earth metals (Group 2), common non-metals in Group 16, thehalogens (Group 17), the noble gases (Group 18) and the transition metals.
C2.4 Know and use the relationship between the position of an atom in the Periodic Table (Group and Period) and the electron configuration of the atom.
C2.5 Understand that elements in the same Group have similar chemical properties and that down a metal Group, reactivity increases and down a non-metal Group, reactivity decreases.
C14.1 Understand that the reactivity of a metal is linked to its tendency to form positive ions and the ease of extraction of the metal.
C14.2 Be able to use displacement reactions to establish the order of reactivity of metals and vice versa.
C14.3 Describe how the uses of metals are related to their physical and chemical properties. e.g. Al, Fe, Cu, Ag, Au, Ti, and understand that alloys can be formed to produce meterials with specific properties.
C14.4 Know that most metal ores are the oxides of the metal, and that the extraction of metals always involves reduction processes.
C14.5 Know that common properties of transition metals include:
- they are able to form stable ions in different oxidation states
- they often form coloured compounds
- they are often used as catalysts (as ions or atoms)
