Easy for elements to loose an electron Shiny, soft, not free, REACTIV | Group 1: Alkali Metals |
Hard, dense, strong, high melting point, not free, less reactiv | Group 2: Alkaline Earth Metals |
Unique among elements, Does not share group 1 Electron configuration= 1s^1 | Hyrdogen |
Only element stable with 2 electrons, like noble gases (nonreactive), | Helium |
Typical metal, less reactive that 1 &2 Gold, palladium, Platinum= least reactive | D-group (3-12): transition Metals |
Total number of electrons in the valence= g#-10 Properties vary: metals, metalloids, non-metals, gases | P-block(13-18): Main Group elements |
Most reactive non metals, 7 valence e/wants one more, but super reactive | Halogens: group 1 and 17 |
Lanthanides: Shiny Metals Actinides: Radioactive, first four natural Sideways- no rules | F-Block |
