Two action-packed distance or remote learning packages for middle school which cover the periodic table and the properties of metals and non - metals

Each resource has been designed so that the animated PowerPoint replaces the teacher by providing structure, sequence, knowledge and answers. It gives advice on how to use distance learning successfully and guides the learner step-by-step through the topic. The supporting worksheets include guided notes, cut-outs, foldables digital quick-tests, fact sheets and progress checks to provide a familiar medium for students to develop and test their knowledge and to continue to develop their literacy skills and use their creativity to organise their learning and assess their progress.

What’s Covered

• Metals and Non – metals
• Metals are conductors of electricity and heat while non - metals are insulators.
• Metals are strong (have high tensile strength) but non - metals are not.
• Metals are shiny when freshly cut or polished but non -metals are dull.
• Metals are sonorous (make a ringing noise when struck while non – metals do not.
• Metals are malleable (can be beaten into shape) and ductile (can be drawn into wires) but non – metals are neither and are brittle (shatter when struck.
• Iron, nickel and cobalt are magnetic but all non – metals are not magnetic.
• Metals are heavy which means they have a high have a high density because they contain a lot of particles. Non – metals are not heavy.
• Metals are all solids at room temperature, except for mercury which is a liquid, as they have high boiling and melting points. Of seventeen non - metals, all are gases except for five which are solids and one which is a liquid.
• Both metals are non – metals burn in oxygen to form the oxide.
• Metal oxides are alkaline and non -metal oxides are acidic.

Periodic Table

• Elements are arranged in the periodic table in order of atomic number.
• Metals are on the left of the table and non – metals on the right with a zig – zag line dividing the two.
• Some of the metals touching the zig – zag line are semi – metals or metalloids which means they have some properties of metals and of non – metals.
• Vertical columns are called groups and horizontal rows are called periods.
• Each period starts with metals on the left and end with non – metals on the right.
• The elements within each group have similar physical and chemical properties.
• Group 1 are the alkali metals. Group 2 are the alkaline earth metals. Group 7 are the halogens. Group 0 are the rare or noble gases. The central block are the transition metals.
• On the left – hand side of the table, reactivity increases as you go down a group and on the right – hand side of the table reactivity increases as you go up a group.
• Group 1: can be cut with a knife; must be stored under oil; low density – lithium, sodium and potassium float on water; form compounds which are solid at room temperature; form compounds with similar formulae – LiCl. NaCl. Group 7;are all coloured; react with hydrogen to form acids; react with metals to form salts.
• Alkali metal + water  alkali metal hydroxide + hydrogen
• lithium + water  lithium hydroxide + hydrogen
• Group 0 are all inert gases – they do not react with other elements
• Transition metals; except for mercury, which is a liquid, these are harder than group 1 metals; have high melting points; react slowly with atmospheric oxygen.
