nickelHard, malleable and ductile, silver-white, metallic element, atomic number 28, relative atomic mass 58.71. It occurs in igneous rocks and as a free metal (native metal), occasionally occurring in fragments of iron–nickel meteorites. It is a component of the Earth's core, which is held to consist principally of iron with some nickel. It has a high melting point, low electrical and thermal conductivity, and can be magnetized. It does not tarnish and therefore is much used for alloys, electroplating, and for coinage. It was discovered in 1751 by Swedish mineralogist Axel Cronstedt (1722–1765) and the name given is an abbreviated form of kopparnickel, Swedish ‘false copper’, since the ore in which it is found resembles copper but yields none.

"You ought to get a good one for that," she laughed,--"all bright parts nickel, I suppose; indeed, you should get a real silver frame and gold handle-bars for that, don't you think? The room was large, and sombre with dark woods and hangings like the hall; but through the west window the sun threw a long shaft of gold across the floor, gleamed dully on the tarnished brass andirons in the fireplace, and touched the nickel of the telephone on the great desk in the middle of the room. The stove was very large, with bright nickel trimmings, and behind it there was a long wooden bench against the wall, and a tin washtub, into which grandmother poured hot and cold water. |
