Chapters 5-7

Using all of your materials from previous chapter complete the following:

Chapter 5 The Periodic Table

Use the following answers for questions 1-6
a. Fluorine / b. Oxygen / c. Nitrogen / d. Carbon / e. Aluminum
f. Magnesium / g. Lithium / h. Iron / i. Hydrogen / j. none of these
1. Which of the elements is an alkali metal?
2. Which of the elements is a transition metal?
3. Which is an Alkaline Earth metal?
4. Which is the basis for all life on the planet?
5. Which is the most abundant element in the universe?
6. Which is the most abundant element in the Earth’s crust?
Fill in the chart
The object of this question is to use the periodic properties of the elements to fill in the chart found on the answer sheet. The code letters A to Z have been assigned to the first representative 26 elements (transition elements are not included) on the periodic chart. The code letters do not represent certain chemicals symbols (that is, C is not carbon), nor have the letters been assigned in alphabetical order. These letters are presented in families, and your task is to arrange these letters in the proper sequence on the blank periodic table. To do this, use the clues given which pertain to certain members of each family. The numbers in each square on the table are the atomic numbers of the elements.
The best way to start is to use the clues to find in which group each family of elements belongs, and then to arrange the elements within the family using the other clues. The following elements belong together in families: CYDA, RUPF, GWI, MNX, LEQ, KSO, HBZ, and VJT

D is the most reactive of the alkali elements

/ 11. J has more protons than V
2. Element A is a gas at room temperature / 12. P has 1 less proton than D
3. H has 4 electrons in a neutral atom / 13. R has 8 more electrons than F
4. M has the fewest energy levels in its family / 14. Element E has 1 more proton than H
5. L has a larger atomic mass than Q / 15. Z is the alkaline earth metal with the largest atomic mass.
6. S has the fewest energy levels in its group / 16. G has 15 protons
7. E has 3 valence electrons / 17. Atoms of G are smaller than W but larger than I
8. C has one less proton than H / 18. K has 16 protons
9. X has the largest number of protons of its group / 19. T is the most reactive halogen
10. U is the largest inert element
