Nickel is a silverywhite metal with a slight golden tinge that takes a high polish. It is one of only four elements that are magnetic at or near room temperature, the others being iron, cobalt and Curie temperature is 355 °C (671 °F), meaning that bulk nickel is nonmagnetic above this temperature. The unit cell of nickel is a facecentered cube with the lattice parameter of ...
