Groups/Families
-Columns on the Periodic Table
Elements have the same number of valence electrons
Element Categories
-Metals
-Non-metals
-Metalloids
Metals
-Solid, lustrous, malleable, ductile, good conducters of electricity and heat
-Lose electrons in chemical reaction
Non-metals
-Brittle (not malleable or ductile), varying states of matter, poor conductors of heat and electricity
-Gain electrons in chemical reaction
Metalloids
-Staircase formation on the Periodic Table
-Appear like/have physical properties of metals (lustrous, silvery, solid)
-Appear like/have chemical properties of non-metals
-Semi-conductors (partially conduct electricity- often used to make computer chips)
