Ch 6 review

1. Ch 6 review

2. Who was responsible for creating the first organization of the periodic table • Moseley • Dalton • Mendeleev • Rutherford

3. How was the first periodic table organized • By increasing atomic number • By increasing number of electrons • By increasing mass number • By increasing atomic mass

4. The number of valance electrons • Is the same as the protons • Is the electrons in the outer energy level • Is the electrons in the inner energy level • Does not change in a period

5. Vertical columns on the periodic table are called • Groups • Periods • Rows • halogens

6. As you go across a period • Valance electrons increase • Valance electrons stay the same • Metallic properties increase • Atomic size increases

7. Participant Leaders

8. This person organized the periodic table we currently use • Moseley • Dalton • Mendeleev • Rutherford

9. When a metal and a nonmetal bond • The metal takes e- from the NM • The NM takes e- from the metal • The e- are shared • e- are not transferred

10. What group is entirely radioactive • Halogens • Lanthanides • Alkalis • Actinides

11. Metals can be found on • The left of the table • The right of the table • The stair-step line • All elements that are solids

12. This word means to be hammered into thin sheets • Ductile • Malleable • Luster • inert

13. How many valance electrons do alkaline earth metals have • 1 • 2 • 5 • 7

14. Participant Leaders

15. This word means will not react • Malleable • Luster • Inert • radioactive

16. A salt is formed between • An alkali metal and a halogen • An alkaline earth metal and a Nobel gas • Rare earth elements • Transition metals

17. This element is in group 6 period 4 • Cr • Hf • Sg • Uun

18. This element is a semiconductor that has more protons than titanium but less valance electrons than oxygen • Antimony • Boron • Polonium • silicon

19. Elements in this group react violently with water to lose one electron • Nobel gasses • Halogens • Alkali metals • Transition elements

20. Participant Leaders

21. This group of elements have luster, and conduct electricity • Metals • Metalloids • Nonmetals • halogens

22. This group of elements typically will share electrons • Group 1 • Group 2 • Group 16 • Groups 18

23. This element is a transition metal • Tungsten • Lithium • Boron • Xenon

24. These elements might be shiny or dull, and are not great at conducting heat • Metals • Nonmetals • Metalloids • Rare earth metals

25. This element has more valance electrons than oxygen, less protons than krypton and is in period 3 • Fluorine • Chlorine • Lithium • sodium

26. This semiconductor is in period 7 • Lead • Bismuth • Polonium • Astitine

27. Participant Leaders

28. To be stretched into thin wires is • Malleable • Ductile • Luster • inert

29. The periodic table we currently used is organized by a main property, and a secondary which are • Atomic size and atomic number • Atomic number and atomic mass • Atomic mass and number of electrons • Atomic number and mass number

30. This group is unlikely to react with any other elements • Nobel gasses • Halogens • Alkali metals • Transition metals

31. An element with 7 valance electron most likely belongs to group • 18 • 17 • 7 • 1

32. This group needs to loose 2 valance electrons to have a full outer shell • Group 1 • Group 2 • Group 16 • Group 17

33. This element is a rare earth metal • Neodymium • Barium • Potassium • Nickel
