3. (8th) Chapter 4-3 Cornell Notes Key Terms metal malleable ductile thermal conductivity electrical conductivity reactivity corrosion alkali metal alkaline earth metal transition metal particle accelerator

5. (8th) Chapter 4-3 Cornell Notes most elements metals, based on properties; Paragraph 1 Properties: luster, malleability, ductility, conductivity; malleable: made into flat sheets/other shapes; ductile: pulled out/drawn into wire; thermal conductivity: object’s ability to transfer heat; electrical conductivity: object’s ability to transfer electrical current; some metals good conductors ; some also magnets. 1.511 × 511 - en.wikipedia.org511 × 511 - en.wikipedia.org

6. (8th) Chapter 4-3 Cornell Notes Reactivity : ease/speed combine w/ other elements, compounds; corrosion: metal reacts w/oxygen. Paragraph 2

7. (8th) Chapter 4-3 Cornell Notes metals in a family similar properties; reactivity decreases moving from left to right across the table. Paragraph 3

8. (8th) Chapter 4-3 Cornell Notes Group 1 alkali metals; so reactive never uncombined in nature. Paragraph 4

9. (8th) Chapter 4-3 Cornell Notes Group 2 alkaline earth metals; also never uncombined in nature. Paragraph 5

10. (8th) Chapter 4-3 Cornell Notes Groups 3-12 transition metals; bridge between reactive and non-reactive metals/elements. Paragraph 6

11. (8th) Chapter 4-3 Cornell Notes Groups 13-15 include metals, non- metals, metalloids; not as reactive. Paragraph 7

12. (8th) Chapter 4-3 Cornell Notes elements below main table = lanthanides, actinides; lanthanides + metals = alloys; many actinides synthetic elements, formed by crashing nuclear particles into each other. Paragraph 8
