Across
  1. 2. Potential Energy,
  2. 5. electron, is the outermost electron(s) of an atom that are involved in chemical bonding
  3. 6. table, is a tabular arrangement of chemical elements organized by increasing atomic number, which is the number of protons in an atom's nucleus
  4. 7. reaction, heat is released to the surroundings because the reaction products are at a lower energy level than the reactants.
  5. 9. is a negatively charged ion
  6. 10. energy, is the total kinetic energy possessed by all of the individual particles that make up an object or substance.
  7. 12. refers to the emission and transmission of energy in the form of waves or particles through space or a medium
  8. 15. is energy that transfers from one object to another because of a temperature difference between the objects
  9. 17. configuration, is the the positioning of electrons in an atom or molecule
  10. 20. a property of a substance or object that is large enough to see or measure without magnification
  11. 22. are held together by chemical bonds, which form through the electrical attraction between protons and electrons.
  12. 24. is the study of energy changes that happen during chemical reactions and changes in state.
  13. 26. is an ion that has a positive charge
  14. 27. are areas around the nucleus of an atom where electrons are most likely to be found
  15. 29. Potential Energy, A hammer raised by a cam on a turning wheel gains gravitational potential energy. When it drops, potential energy is converted to kinetic energy.
  16. 31. is a measure of the average kinetic energy of the particles in matter
  17. 32. refers to the number of complete waves, or cycles, that pass a given point in a specific amount of time, usually per second
Down
  1. 1. refers to the distance between two consecutive peaks or troughs in a wave
  2. 3. potential energy, The energy stored in chemical bonds
  3. 4. Energy, The energy of an object's motion is called kinetic energy.
  4. 8. is the capacity to move, do work, change matter, or produce heat.
  5. 11. kinetic energy, is the mathematical average of the individual kinetic energies of all the particles in a substance or object.
  6. 13. typically refers to the maximum extent of a wave's displacement from its rest position
  7. 14. Same atomic number but different masses in each item
  8. 16. refers to the transfer of heat through the movement of fluids (liquids or gases)
  9. 18. of conservation of mass, energy can neither be created nor destroyed in a physical change or chemical reaction.
  10. 19. is an atom or molecule that has gained or lost one or more electrons, that’s creates a positive or negative charge
  11. 21. refers to the process by which heat or electricity is transmitted through a substance
  12. 23. flow, is the rate at which heat moves from one substance to another
  13. 25. reaction, heat is absorbed from the surroundings because the reaction products are at a higher energy level than the reactants.
  14. 28. Energy, The energy stored within a system due to the positions of its parts
  15. 30. number, the number of protons in the nucleus of an atom
