Atoms Elements Compounds Mixtures @ AJHS NZ
| Question | Answer |
|---|---|
| alloy | A mixture of different metals. |
| atom | The smallest part of an element you can get. |
| boiling point | When a liquid is at its boiling point it is as hot as it can get. It is evaporating as fast as it can. |
| bond | Force holding atoms together. |
| calcium | A metal which reacts easily with water. |
| chemical formula | A combination of symbols and numbers that shows how many atoms of different kinds there are in a particular molecule. In compounds that do not form molecules, it shows the ratio of elements in the compound. |
| chromatography | Separating dissolved solids from one another. The solids are usually coloured. |
| compounds | Substances that can be split up into simpler substances. |
| decompose | Break down into simpler parts. |
| distillation | Separating a liquid from a solution by evaporating the liquid and then condensing it. |
| electrical conductor | Something which allows electricity to flow through it easily. |
| element | All the atoms in an element are the same. A substance that cannot be split up into anything simpler by chemical reactions. |
| evaporate | When a liquid turns into a gas. |
| freezing point | The temperature at which a liquid turns into a solid. |
| heat conductor | Something which allows heat to flow through it easily. |
| high melting point | Something with a high melting point has to be at a very high temperature before it melts. It is a solid at room temperature. |
| irreversible change | Permanent change. |
| low boiling point | Something with a low boiling point will turn into a gas at a relatively low temperature. It can be a solid, liquid or gas at room temperature. |
| magnetic | A metal (iron, nickel or cobalt) that can be magnetised or attracted to a magnet. |
| melting point | The temperature at which a solid turns into a liquid. |
| metals | Elements that are shiny, conduct heat and electricity well, and often have high melting and boiling points. |
| mixture | Two or more different kinds of particles that are not chemically joined to each other. |
| molecule | Two or more atoms joined together. |
| non-metals | Elements that are not shiny, and do not conduct heat and electricity well. |
| oxide | A compound that includes oxygen. |
| Periodic Table | Table that shows all the elements. |
| physical change | A change where no new substances are formed. |
| potassium | Soft, shiny, reactive, silver-coloured metal. |
| precipitate | Insoluble solid produced by mixing two solutions. |
| product | New chemical formed in a chemical reaction. |
| properties | Ways of describing a substance. |
| pure | A substance that does not have anything else in it. |
| reactants | Chemicals that join together to form a new substance. |
| shiny | Reflects light well. |
| sodium chloride | Chemical name for common salt. |
| sulphur | A yellow, non-metal element. Solid at room temperature |
| symbol equation | A way of writing out what happens in a chemical reaction using the symbols that represent the substances involved. |
| symbol | The letter or letters that represent an element. |
