USING THE PERIODIC TABLE
Part 1 - Match each of the following elements with the element in the list that has the most similar chemical properties. Use the Periodic Table as a guide.
(F) vanadium (V)
(K) rhenium (Re)
(B) helium (He) (G) phosphorus (P) (L) oxygen (O)
(C) potassium (K) (H) gold (Au) (M) yttrium (Y)
(D) rhodium (Rh) (I) indium (In) (N) silicon (Si)
(E) terbium (Tb) (J) chlorine (Cl) (O) radium (Ra)
____ 1. cobalt (Co) ____ 9. manganese (Mn)
____ 2. carbon (C) ____ 10. niobium (Nb)
____ 3. argon (Ar) ____ 11. calcium (Ca)
____ 4. cerium (Ce) ____ 12. scandium (Sc)
____ 5. lithium (Li) ____ 13. mercury (Hg)
____ 6. aluminum (Al) ____ 14. selenium (Se)
____ 7. iodine (I) ____ 15. arsenic (As)
____ 8. copper (Cu)
Part 2 - Modified True or False - If the statement is false, replace the underlined word with a word that makes the statement true.
____________________ 16. The electron configurations of all elements in Group 1 end in s1.
the electron configuration for the outer energy level of potassium, 4s1,
coefficient 4 indicates the group number.
such as silicon are called metalloids because they have properties of both
metals and nonmetals.
____________________ 19. Atoms with full outer energy levels are very reactive.
____________________ 20. Elements with three or fewer electrons in the outer energy level are usually metals.
