Across
  1. 2. A chemical reaction in which an acid and a base react to produce salt and water
  2. 3. The force exerted per unit area on a surface
  3. 10. An incredibly small, negatively charged subatomic particle
  4. 11. A positively charged subatomic particle
  5. 12. The first column (Group 1) elements in the periodic table. They are very reactive metals that easily lose one electron to become positively charged ions
  6. 14. A set of four numbers (n, l, ml, and ms) that define the energy level, orbital shape, and spin of an electron within an atom
  7. 16. Letters used in chemical equations to show the physical state of a substance (s - solid, l - liquid, g - gas, aq - aqueous)
  8. 18. Whole numbers in a chemical equation that represent the relative quantities of reactants and products involved in the reaction
  9. 20. The relative amount of a specific isotope found within a sample of a particular element
  10. 22. A concentration unit indicating the number of moles of a solute dissolved in one liter of solution
  11. 23. Difference of electronegativity within a molecule. This arises because some atoms attract electrons more strongly than others
Down
  1. 1. The subatomic particles occupying the outermost energy level of an atom. These are primarily responsible for chemical bonding with other atoms
  2. 4. The specific arrangement of electrons in the various energy levels and orbitals of an atom
  3. 5. The amount of solute (dissolved substance) present in a given amount of solvent or solution
  4. 6. The unreactive elements in Group 18 of the periodic table
  5. 7. The elements in Group 17 of the periodic table
  6. 8. A positively charged ion created when an atom loses one or more electrons
  7. 9. The amount of three-dimensional space occupied by a substance
  8. 11. A chart that organizes elements based on their atomic number (number of protons), electron configuration, and repeating chemical properties
  9. 13. Variations of an element with the same number of protons but a different number of neutrons in their nucleus
  10. 15. A charged ion formed by the covalent bonding of two or more different atoms
  11. 17. A horizontal row in the periodic table
  12. 19. The unit of temperature on the thermodynamic temperature scale
  13. 21. The fundamental unit of matter
