What is Metal?
A metal is a material (element, compound, or alloy) that typically exhibits high electrical conductivity, thermal conductivity, metallic luster, malleability, ductility, and the ability to form positive ions (cations). About 80% of all chemical elements are metals. Metallic bonding involves a "sea of electrons" delocalised through a lattice of positive metal ions. Metals are found in Groups 1, 2, and 3–12 (transition metals) plus many in groups 13–16.

Construction (iron/steel, aluminum). Electrical wiring (copper, aluminum). Jewelry (gold, silver, platinum). Electronics (silicon, germanium, copper, gold). Coinage (gold, silver, copper). Catalysis (Ni, Pd, Pt). Medical implants (titanium, stainless steel). Batteries (Li, Zn, Pb, Ni).
Toxic heavy metals: Pb, Hg, Cd, As, Tl, Be (severe health hazards). Reactive metals: alkali metals react violently with water. Metal dusts: fire/explosion risk. Metal fumes from welding: metal fume fever (Zn), carcinogens (Ni, Cr(VI), Cd). Individual metal safety varies enormously.
