Describe changes of state in terms of melting, boiling, evaporation, freezing, condensation and sublimation 1(S)Explain changes of state in terms of the kinetic theory
3.1 State the relative charges and approximate relative masses of protons, neutrons and electrons Define proton number (atomic number) as the number of protons in the nucleus of an atom Define nucleon number (mass number) as the total number of protons and neutrons in the nucleus of an atom Use proton number and the simple structure of atoms to explain the basis of the Periodic Table (see section 9), with special reference to the elements of proton number 1 to 20 Define isotopes as atoms of the same element which have the same proton number but a different nucleon number 3.1(S)Understand that isotopes have the same properties because they have the same number of electrons in their outer shell 3.1 State the two types of isotopes as being radioactive and non-radioactive; State one medical and one industrial use of radioactive isotopes 6.2 Describe radioactive isotopes, such as 235U, as a source of energy 3.1 Describe the build-up of electrons in ‘shells’ and understand the significance of the noble gas electronic structures and of the outer shell electrons 3.1(S)Understand that isotopes have the same properties because they have the same number of electrons in their outer shell 3.2.1 Describe the differences between elements, mixtures and compounds, and between metals and non-metals 7.1 Identify physical and chemical changes, and understand the differences between them 3.2.1Describe an alloy, such as brass, as a mixture of a metal with other elements 10.1 Identify representations of alloys from diagrams of structure 3.2.2. Describe the formation of ions by electron loss or gain; Describe the formation of ionic bonds between elements from Groups I and VII 3.2.2(S)Describe the formation of ionic bonds between metallic and non-metallic elements; Describe the lattice structure of ionic compounds as a regular arrangement of alternating positive and negative ions 6.1 Describe the meaning of exothermic and endothermic reactions 9.1Describe the Periodic Table as a method of classifying elements and its use to predict properties of elements 9.2 Describe the change from metallic to non-metallic character across a period 9.2(S)Describe and explain the relationship between Group number, number of outer shell electrons and metallic/non-metallic character 4.1Use the symbols of the elements and write the formulae of simple compounds; Deduce the formula of a simple compound from the relative numbers of atoms present 9.3 Describe lithium, sodium and potassium in Group I as a collection of relatively soft metals showing a trend in melting point, density and reaction with water; Predict the properties of other elements in Group I, given data, where appropriate.
