Other Experimental
Lustrous, ductile, malleable metal; Mohs' hardness: 3.0; specific resistance: 1.673 microohm/cm; heat of fusion: 48.9 cal/g; heat capacity (solid): 0.092 cal/g/deg C at 20 °C, (liq): 0.112 cal/g/deg C; becomes dull when exposed to air; two naturally occurring isotopes: 63 (69.09%), 65 (30.91%); 9 artificial isotopes;Very slowly attacked by cold hydrochloric acid or dil sulfuric acid; readily by dil nitric acid, and by both not conch sulfuric acid and hydrobromic acid. It is also attacked by acetic acid and other organic acids.;COPPER FORMS TWO SERIES OF SALTS, CU(1+) AND CU(2+) BOTH VALENCE TYPES FORM COMPLEX IONS THAT ARE STABLE.;Ductile, excellent conductor of electricity. Complexing agent, coordination numbers 2 and 4. More resistant to atmospheric corrosion than iron, forming green layer of hydrated basic carbonate. Readily attacked by alkalies. Noncombustible, except as powder.;ELECTRONEGATIVITY (PAULING SCALE): 1.90;Dissolved readily in nitric acid and hot concentrated sulfuric acids slowly, but only when exposed to the atmosphere.
