Where can you find the element nickel?
Nickel is one of the primary elements of the Earth’s core which is thought to be made mostly of nickel and iron. It is also found in the Earth’s crust where it is about the twenty-second most abundant element. Most nickel that is mined for industrial use is found in ores such as pentlandite, garnierite, and limonite.

What are facts about the element nickel?
Nickel Facts. Nickel is atomic number 28 with element symbol Ni. Nickel is a hard, ductile solid at room temperature. Like other transition metals, it has high melting and boiling points, high density, and conducts electricity. Its melting point is 1728 K (1455 °C, 2651 °F) and its boiling point is 3003 K (2730 °C, 4946 °F).
