Chromium vs. Nickel — What's the Difference?

Chromium is a chemical element with the symbol Cr and atomic number 24. It is the first element in group 6.

Nickel is a chemical element with the symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge.

A lustrous, hard, steel-gray metallic element, resistant to tarnish and corrosion and found primarily in chromite. It is used in the hardening of steel alloys and the production of stainless steels, in corrosion-resistant decorative platings, and as a pigment in glass. Atomic number 24; atomic weight 51.996; melting point 1,907°C; boiling point 2,671°C; specific gravity 7.15; valence 2, 3, 6. See Periodic Table.

A silvery-white metal, the chemical element of atomic number 28.

A chemical element (symbol Cr) with an atomic number of 24: a steely-grey, lustrous, hard and brittle transition metal.

A five-cent coin; five cents

A comparatively rare element occurring most abundantly in the mineral chromite. Atomic weight 52.5. Symbol Cr. When isolated it is a hard, brittle, grayish white metal, fusible with difficulty. Its chief commercial importance is for its compounds, as potassium chromate, lead chromate, etc., which are brilliantly colored and are used dyeing and calico printing. Called also chrome.

Coat with nickel

A hard brittle blue-white multivalent metallic element; resistant to corrosion and tarnishing

Symbol Ni A silvery, hard, ductile, ferromagnetic metallic element used in corrosion-resistant alloys, stainless steel, catalysts for hydrogenation, and batteries, and for electroplating. Atomic number 28; atomic weight 58.69; melting point 1,455°C; boiling point 2,913°C; specific gravity 8.902; valence 0, 1, 2, 3. See Periodic Table.
