4.1 Metals (Properties and Bonding)

Flashcards about properties and bonding of metals

Metals [generally]

Exhibit a range of boiling points and relatively high boiling points, good conductors of electricity, good conductors of heat, have high densities

Iron is…

Soft, malleable, magnetic, good thermal and electrical conductor, fairly reactive, readily forms alloys

Aluminum is…

Low density, relatively soft when pure, excellent thermal and electrical conductor, malleable and ductile, good reflector of heat and light, readily forms alloys

Titanium is…

Very strong, high melting point, low density, low reactivity, readily forms alloys

Gold is…

Shiny gold appearance, excellent thermal and electrical conductor, unreactive, readily forms alloys

Aluminum is used in…

Saucepans, frying pans, drink cans, cooking foil, food packaging, roofing, window frames, appliance trim, decorative furniture, electrical cables, aircraft and boat construction

Titanium is used in…

Medical devices within the body, wheelchairs, computer cases; lightweight alloys are used in high-temperature environments such as spacecraft and aircraft

Gold is used in…

Electrical connections, jewelry, monetary standard, dentistry

Metals are malleable, meaning…

They can be shaped by beading or rolling

Metals are ductile, meaning…

They can be drawn into a wire

Compared to Group 1 and 2 metals, transition metals…

They tend to be harder, have higher densities, have higher melting points

Transition metals are…

Silver-colored and similar in appearance, between group 2 and group 13, generally have unfilled d-subshells
