Luster – shiny. • Ductile – drawn into wires. • Malleable – hammered into sheets. • Conductors of heat and electricity. Metals
Non-metals • Dull • Brittle • Nonconductors- insulators
Metalloids or Semimetals • Properties of both • Semiconductors
1 • Group 1 are the alkali metals • They have 1 valence electron in the outer orbital or energy shell
Group 2 are the alkaline earth metals • They have 2 valence electrons 2
Transition metals • Groups 3-12 • their properties do not fit in with those of any other family.
Group 13 is called the Boron family • They have 3 valence electrons 13
Group 14 is called the Carbon Family • They have 4 valence electrons 14
Group 15 is called the Nitrogen Family • They have 5 valence electrons 15
Group 16 is called the Oxygen Family • They 6 valence electrons 16
Group 17 is called the Halogens • They have 7 valence electrons 17
Group 18 are the Noble Gases • They have 8 valence electrons
