chem quiz meatal vs nonmetals

characteristics of metallic

1. most of them are solids at stp

2. most have densities greater than water (group 1 is less dense than water

3. malleable= flat layers

4. ductile = drawn into wire

5. high luster= shinny

6. good conductors of heat and electricity

7. they have low ionization energy + low electronegativity values

8. metals lose electrons to form cations with smaller atomic radii

charaterica of non metals

1. most are gasses at STP

2. brittle

3. dull=not shinny

4. insulators = poor conductors of heat and electricity

5. gain electrons to form anions (- ions_ with larger atomic radii)

6. high ionization + high electronegativity values
