Across
- 2. Provides the ability to express really small and really large numbers using the power of 10
- 4. Describes a substances potential for a chemical reaction to occur
- 5. Their properties are dependent on the environmental conditions, and they are found between the metals and nonmetals
- 8. Determined using isotopes and their abundances
- 9. The periodic repetition of elements physical and chemical properties
- 12. Energy required to remove an electron from an atoms PEL; the greater the value the more difficult it is to remove an electron (why anions have negative charges) and is affected by atom size and number of protons
- 13. Number of protons, provides identity of element
- 15. Regarding the ability to repeat an outcome (data point)
- 16. Organized the periodic table by increasing atomic number, what the present periodic table is organized by
- 17. Variable that is observed or measured during the experiment and is graphed on the y-axis
- 23. Mixture is uniform in composition, particles are so small that they will not fall out of suspension, known as solutions
- 26. Variable whose value determines the value of another variable, determined prior to the experiment and is graphed on the x-axis
- 28. Size of an atom; increases with the addition of another PEL and decreases due to the increase in the attractive force electrons feel towards the nucleus due to a greater number of protons
- 30. Shows mathematical relationships and provides a picture of the data
- 33. Element or compound, can not be separated by physical means
- 35. Particles are large and will settle in a short time period
- 39. Mass is neither created nor destroyed, it only changes form
- 41. Amount of stuff in a given space or the ratio of mass to volume
- 42. Ordered arrangement of particles in a solid crystalline structure
- 43. Quality or condition that can be observed or measured without changing a substances composition
- 44. Organized the periodic table by increasing atomic mass
- 45. 2 or more substances mixed in unfixed proportions, can be separated by physical properties
- 46. Particles have NO order and interaction with one another (high energy and no attraction)
- 50. Total mass of an atom and is equal to the protons plus the neutrons
- 51. Mixture is not uniform in composition, particles will vary in size and therefore will fall out of suspension
- 53. Dependent on the amount of matter in a sample, example would be mass
- 54. Composition of the matter changes
- 55. Manipulation of a substance while maintaining composition
- 56. Ability of an atom to attract electrons when in a compound; smaller the atom and least number of protons will give a greater draw to other electrons
Down
- 1. Logical, systematic approach to the solution of a problem
- 3. Dependent on the type of matter in the sample, example would be melting point
- 6. Mathematical process that uses ratios or equalities to move from one unit system to another
- 7. Number in standard notation will be less than one
- 10. Column on the periodic table, also known as Family
- 11. Number in standard notation will be greater than one
- 14. Prediction inside the data set
- 18. Used to validate the accuracy of an experiment
- 19. Matter is composed on tiny particles in motion
- 20. Particles are less close together with less order, demonstrate “flow” (moderate kinetic energy and moderate attraction)
- 21. Particles are small enough that it takes long time periods for settling to occur
- 22. Separates a solid from a liquid
- 24. 2 or more elements chemically bonded together in fixed proportions, can be broken down into elemental components
- 25. Anything that has mass and takes up space
- 27. Separates components from a solution
- 29. 80% of the elements are within this class; they are good conductors, and most are solids at room temperature
- 31. Regarding the ability to meet a desired goal (data point)
- 32. Prediction outside of the data set
- 34. Determined by the tool being used and must be honored throughout calculations
- 36. Shows relationships between 3 phases of a substance and provides specifics regarding temperature and pressure conditions for each phase
- 37. Most are found in the upper right corner of the periodic table; they are bad conductors, and most are gases at room temperature
- 38. A row on the periodic table
- 40. Particles are packed tightly together in ordered arrangement (low kinetic energy and high attraction)
