Post-transition metal packing structure. Tin forms Zintl phases such as NaSn, BaSn, KSn and CaSn. It has good corrosion resistance in air on account of forming a thin protective oxide layer. Pure tin has no structural uses. It is used in lead-free solders, and as a hardening agent in alloys of other metals, such as copper, lead, titanium and zinc. Lead is a soft metal (MH 1.5, but hardens close to melting) which, in many cases, is unable to support its own weight. It has a close-packed structure (BCN 12) but an abnormally large inter-atomic distance that has been attributed to partial
Electrical connector other connectors such as Banana connectors. A connector that locks a metal spade to a terminal by screwing them together. Crimp connectors can be used for fast and friction-type connections in DC applications where connections are broken repeatedly. Alligator connectors are often used as temporary test leads. A screw terminal is a type of electrical connector where a wire is held by the tightening of a screw. Phone connectors can be used as connectors in microphone cables and for low-voltage, low-current applications. Pogo Pin Connectors or Spring Loaded Connectors is a connector type commonly used in consumer products. The Connector
