This course covers IGCSE Grade-8 Chapter- Metals & Reactivity Series
This course will teach you ……
– Understand & Define metals, non metals ,Metaloids and Alloys
– Physical properties of the metals
– Difference Between Metals & non metals
– Difference Between Alkali Metals & Transition metals
– Explain the uses of Metals and their Alloys, in terms of their properties.
– Compositions of some important ALLOYS
– Understands that metals can be arranged in a reactivity series based on the reactions of the metals and their compounds: Potassium, Sodium, Lithium, Calcium, Magnesium, Aluminium, Zinc, Iron, Copper, Silver and Gold
– Describe how reactions with Water and dilute acids can be used to deduce the following order of reactivity: Potassium, Sodium, Lithium, Calcium, Magnesium, Zinc, Iron, and Copper
– Deduce the position of a metal within the reactivity series using displacement reactions between metals and their oxides, and between metals and their salts in aqueous solutions
– Definition and Balance Equation of rust
– Describe the conditions under which Iron rusts
– Describe how the rusting of Iron may be prevented by grease, oil, paint, plastic and galvanising
– Understand the sacrificial protection of Iron in terms of the reactivity series
