Across
- 6. A unit used to measure the amount of a substance, equal to Avogadro's number (6.022 × 10²³ particles).
- 8. A substance that donates a proton (H⁺) to another substance.
- 9. A law stating that mass is neither created nor destroyed in a chemical reaction.
- 12. A substance that accepts a proton (H⁺) from another substance.
- 13. Atoms of the same element that have a different mass due to varying neutron numbers
- 14. Base The species formed when an acid loses a proton (H⁺) in a chemical reaction.
- 15. The species formed when a base gains a proton (H⁺) in a chemical reaction.
Down
- 1. A chemical bond formed by the sharing of electrons between two nonmetal atoms.
- 2. A reaction that absorbs energy (usually in the form of heat) from its surroundings.
- 3. A chemical bond formed by the transfer of electrons from a metal to a nonmetal, creating oppositely charged ions.
- 4. The measurement of disorder
- 5. A substance that increases the concentration of hydrogen ions (H⁺) in an aqueous solution.
- 7. A measure of an atom's ability to attract and bond with electrons in a chemical bond.
- 10. A substance that increases the concentration of hydroxide ions (OH⁻) in an aqueous solution.
- 11. A measure of the acidity or basicity of a solution, calculated as the negative logarithm of the hydrogen ion concentration.
