Atomic Structure and Bonding Matter

Specific Learning Outcomes Classify matter as elements, compounds or mixtures. Identify and name elements by their symbols and place them on the Periodic Table. Classify raw materials as mixtures, pure substances, elements, compounds, metals, non-metals, ionic and covalent, on the basis of their properties.

Early Ideas in Chemistry Aristotle thought that matter was made up of the four elements – Earth, Fire, Air and Water. Chemists study matter. They wonder what it is made of and why one substance can be changed into another. Robert Boyle proposed the idea in 1661 of a new definition of the term ‘element’ Democritus reasoned that matter must be made up of particles.

Matter and Chemistry Matter is anything which has volume or mass. The basic building blocks of all matter are atoms. Most of the matter that we see around us is either: An element A Compound A Mixture An elemen t is a pure substance which is made up of only one type of atom A compound is a pure substance which is made up of two or more elements which have chemically combined in a fixed proportion A mixture is a substance made up of a different combination of elements or compounds mixed together in a variable proportion

Metals and Non-metals Lustrous (shiny) Good conductors of heat and electricity High melting point High density (heavy for their size) Malleable (can be hammered) Ductile (can be drawn into wires) Usually solid at room temperature (an exception is mercury) Opaque as a thin sheet (can't see through metals) Metals are sonorous or make a bell-like sound when struck Not lustrous (dull appearance) Poor conductors of heat and electricity Non-ductile solids Brittle solids May be solids, liquids or gases at room temperature Transparent as a thin sheet Non-metals are not sonorous Fill in your table Level 2 Chemistry Practical Workbook Page 42 Fill in your table Level 2 Chemistry Practical Workbook Page 42 Come up with 5 uses for Metals and Non-Metals to help fill in your table!
