File info: Here's a set of chemistry vocabulary words suitable for a grade 6 level quizlet:1. Element: A pure substance that cannot be broken down into simpler substances by chemical means. Each element is made up of only one type of atom. 2. Atom: The smallest unit of an element that retains the chemical properties of that element. 3. Molecule: A group of two or more atoms held together by chemical bonds. 4. Compound: A substance made up of two or more different elements chemically combined in a fixed ratio. 5. Chemical Reaction: The process by which substances undergo chemical changes, resulting in the formation of new substances with different properties. 6. Physical Change: A change in which the substance's physical properties, such as shape, size, or state, are altered, but its chemical composition remains the same. 7. Chemical Change: A change in which the substance undergoes a chemical reaction, resulting in the formation of new substances with different chemical properties. 8. Solvent: A substance in which other substances can be dissolved to form a solution. Water is a common solvent. 9. Solution: A homogeneous mixture composed of a solute dissolved in a solvent. 10. Solute: A substance that is dissolved in a solvent to form a solution. 11. Density: The measure of how much mass is contained in a given volume of a substance. 12. Evaporation: The process by which a liquid changes into a gas at a temperature below its boiling point. 13. Condensation: The process by which a gas changes into a liquid when it loses heat energy. 14. Melting Point: The temperature at which a solid substance changes into a liquid. 15. Boiling Point: The temperature at which a liquid substance changes into a gas. 16. pH: A measure of the acidity or alkalinity of a solution, ranging from 0 to 14. A pH of 7 is neutral, below 7 is acidic, and above 7 is basic (alkaline). 17. Periodic Table: A tabular arrangement of elements based on their atomic numbers, electron configurations, and recurring chemical properties. 18. Chemical Symbol: A unique abbreviation or shorthand notation used to represent an element. For example, "H" represents hydrogen, and "O" represents oxygen. 19. Reactant: A substance present at the beginning of a chemical reaction that undergoes a change. 20. Product: A substance formed as a result of a chemical reaction. These vocabulary words cover some essential concepts in chemistry at a grade 6 level. They provide a foundation for understanding the properties of matter, changes in substances, and basic chemical reactions. | ||
