| Mechanical Mixture |
A mixture in which you can distinguish between different types of matter |
+
+ | Suspension |
+ A substance made of a liquid or gas that is separated into layers due to gravity when left undisturbed |
+
+
+ | Alloy |
+ A solid solution of 2 or more metals |
+
+
+ | Mixture |
+ A substance that is made up of at least 2 types of particles |
+
+
+ | Qualitative property |
+ A property of a substance that is not measured and doesn't have a numerical value, such as colour, odur, and texture |
+
+
+ | Qualitative observation |
+ An numerical observation |
+
+
+ | Precipitate |
+ A solid that separates from a solution |
+
+
+ | Density |
+ A measure of how much mass is contained in a given unit volume of a substance; calculated by dividing the mass of a sample of its volume (mass/volume) |
+
+
+ | Element |
+ Element An element is made up of the same atoms throughout, and cannot be broken down further |
+
+
+ | Metal |
+ a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity |
+
+
+ | Pure substance |
+ A substance that is made up of only one type of particle |
+
+
+ | Atom |
+ The smallest unit of matter found in substances |
+
+
+ | Solution |
+ A uniform mixture of 2 or more substances |
+
+
+ | Colloid |
+ is substance with small particles suspended in it, unable to be separated by gravity |
+
+
+ | Emulsion |
+ An Emulsion is a mixture of 2 unmixable liquids, in which one liquid is suspended in the other |
+
+
+ | Physical Property |
+ Characteristic of a substance that can be determined without changing the “making up” of the substance |
+
+
+ | Quantitative property |
+ A property of a substance that is measured and has a numerical value such as temperature, height, and mass |
+
+
+ | Quantitative observation |
+ A observation based on our senses |
+
+
+ | Characteristic |
+ A physical property that is unique to a substance and can be used to identify the substance |
+
+
+ | Periodic Table |
+ a table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns. |
+
+
+ | Compound |
+ Compounds are chemically joined atoms of different elements |
+
+
+ | Non-Metal |
+ A substance that isn’t metal |
