Across
- 4. The ability of a substance to dissolve in a solvent, usually expressed as the maximum amount that can dissolve in a specific volume at a given temperature.
- 6. An electron in the outermost shell of an atom that determines its chemical properties and bonding behavior.
- 7. The vertical columns in the periodic table, where elements have similar chemical properties due to the same number of valence electrons.
- 8. A group of highly reactive elements in Group 1 of the periodic table, including lithium, sodium, and potassium.
- 10. Elements that lack metallic properties, generally poor conductors, and can be gases, liquids, or brittle solids, including oxygen, nitrogen, and sulfur.
- 13. A Russian chemist who created the first widely accepted periodic table by arranging elements based on atomic mass and properties.
- 14. The state in which a solution contains the maximum amount of solute that can dissolve at a given temperature and pressure.
- 18. The substance that is dissolved in a solution.
- 19. Elements with properties intermediate between metals and non-metals, found along the "stair-step" line on the periodic table, including silicon and boron.
- 20. A pure substance consisting of only one type of atom that cannot be broken down into simpler substances by chemical means.
- 22. The process of breaking down rocks and minerals into smaller pieces by physical, chemical, or biological means.
- 23. A solution that has a high amount of solute relative to the amount of solvent.
- 25. A group of highly reactive non-metal elements in Group 17 of the periodic table, including fluorine, chlorine, and iodine.
- 26. The breakdown of rocks through chemical reactions, often involving water, acids, or gases, leading to changes in mineral composition.
Down
- 1. A group of elements in Group 2 of the periodic table that are reactive but less so than alkali metals, including magnesium and calcium.
- 2. The mechanical breakdown of rocks into smaller fragments without changing their chemical composition, caused by factors like temperature changes, freezing and thawing, or abrasion.
- 3. A solution that has a low amount of solute relative to the amount of solvent.
- 5. A substance composed of two or more different elements chemically bonded together in a fixed ratio.
- 9. A set of metallic elements located between the transition metals and metalloids, generally softer and having lower melting points, including aluminum, tin, and lead.
- 11. A homogeneous mixture of two or more substances, consisting of a solute dissolved in a solvent.
- 12. A large group of metallic elements in the center of the periodic table (Groups 3-12) known for variable oxidation states and forming colorful compounds.
- 14. A solution that contains more solute than it can normally hold at a given temperature, often achieved by changing conditions like temperature or pressure.
- 15. The horizontal rows in the periodic table, where elements are arranged by increasing atomic number and share the same number of electron shells.
- 16. A homogeneous mixture of two or more substances, consisting of a solute dissolved in a solvent.
- 17. A group of inert, non-reactive elements in Group 18 of the periodic table, including helium, neon, and argon.

- 24. The substance that dissolves the solute to form a solution.
- 27. A combination of two or more substances that are physically blended but not chemically bonded, which can be separated by physical means.
