A concept map is your own expression of the connections between concepts- multiple connections can form between ideas, so there should be lines connecting many things wherever possible. Use the following terms to create a concept map of Grade 10 Chemistry concepts. Include a brief definition/example for each term. -Matter -Atom -Subatomic particles -Metals -Non metals -Pure substances -Mixtures -Physical Properties -Chemical Properties -Physical Changes -Chemical Changes -Types of Reactions -Acid -Base -pH Submit Cancel
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
