Group 1; unstable, highly reactive, likely to bond with other elements; extremely soft metals, abundant in nature; low densities, low melting and boiling points, 1 valence electron
Alkali Metals
Group 2; very reactive, likely to bond with other elements, 2 valence electrons
Alkaline Earth Metals
Group 17; 7 valence electrons, easily bond with alkali metals to make a salt
Halogens
Group 18; 8 valence electrons, non-reactive, stable, high densities, high melting points, colorless, odorless, tasteless

Brittle, not ductile, bad conductors, low luster, gases at room temperature, right side of Periodic Staircase
Nonmetals
Properties of metals and nonmetals, in Periodic Staircase
Metalloids
Groups 1-2,13-18; represent each category of metals, nonmetals, and metalloids, labeled with number and “A” to show how many valence electrons
Representative Elements
Groups 3-12, solid at room temp., labeled with a number and “B” for the number of valence electrons
