Darken in the “stairstep”. This is where the metalloids are located.
Shade in the metalloids. The metalloids are located on either side of the “stairstep”. Aluminum touches the “stairstep” but is NOT considered a metalloid.
Shade in the metals. They are located on the left side of the table. Hydrogen is located on the left side but is NOT a metal. Transition Metals • Inner Transition Metals
Shade in the nonmetals. Nonmetals are located on the right side of the table. Do not forget to shade in Hydrogen, it is the only nonmetal located on the left side of the table. G A S E S N O B L E
Luster: how light reflects off surface (shiny) • Ductile: can be pulled into a wire. • Malleable: can be pressed into thin sheets. • Good conductors of heat and electricity. • Mostly SOLID at room temperature, with the exception of Mercury (Hg) • Have physical properties of both metals and nonmetals. • Found on the “stairstep”. • Boron is at the top of the “stairstep”. • Brittle: can break very easily. • Poor conductors of heat and electricity. • Mostly GAS at room temperature.
Boron: heat resistant alloys, rocket fuel igniter • Silicon: glass, semi-conductors in electronic devices • Arsenic: poison, wood preservation, insecticides • Copper: electrical wires and motors • Gold: jewelry, dental work, electronic devices • Sodium: medicine, agriculture, salt • Oxygen: supports life • Chlorine: water purification, antiseptic • Helium: balloons, cooling medium for large machines

GROUPS/FAMILIES PERIODS 18 7 Elements within the same period have the same number of energy levels or electron shells. They have the same number of valence electrons and have similar chemical properties. Groups 1 and 17 are highly reactive because they either want to give or receive 1 valence electron.
Atomic NUMBER Tells us protons and electrons Element symbol Atomic MASS Protons + Neutrons Element name
