Across
- 2. A substance in which other substances can dissolve to form a solution.
- 5. A state of matter with no fixed shape or volume; its particles are widely spaced and move freely.
- 8. A substance formed when two or more different elements chemically combine in fixed ratios.
- 9. A mixture of two or more elements, with at least one of them being a metal, that exhibits unique properties.
- 11. The mass of an object per unit volume, often used to describe how tightly packed the particles in a substance are.
- 15. Anything that has mass and occupies space; it can exist in various states, such as solid, liquid, or gas.
- 16. The process of changing from a solid to a liquid state due to an increase in temperature.
- 17. The substances that participate in a chemical reaction to produce products.
- 21. An alloy composed of nickel and chromium, used for its resistance to high temperatures and electrical conductivity.
- 22. A subatomic particle found in the nucleus of an atom, with no electric charge.
- 23. A chemical element with the symbol Na and atomic number 11, a soft, silvery-white metal that is highly reactive with water and air.
- 25. An alloy primarily composed of copper and tin, known for its strength and historical use in sculptures and tools.
- 27. Related to or involving substances and processes in the study of chemistry.
- 28. A pure substance made up of only one type of atom, characterized by its unique chemical properties.
- 29. A state of matter with a fixed shape and volume; its particles are closely packed and have a regular structure.
Down
- 1. Connections or links that hold atoms together in molecules.
- 3. A substance with a pH value less than 7, which can donate protons (H+ ions) in a solution.

- 13. A substance with a pH value greater than 7, which can accept protons (H+ ions) in a solution.
- 14. A homogeneous mixture of two or more substances, where one substance (the solute) is dissolved in another (the solvent).
- 18. A subatomic particle orbiting the nucleus of an atom, with a negative electric charge.
- 19. A state of matter with a fixed volume but no fixed shape; its particles are more loosely packed than in a solid.
- 20. A chemical reaction in which a substance reacts with oxygen to produce heat, light, and usually carbon dioxide and water.
- 24. The smallest unit of a chemical compound, consisting of two or more atoms bonded together.
- 26. A process in which substances interact and transform into new substances with different properties.
