Named for Color

Chromium takes its name from the Greek word for color, for the vivid hues of its compounds. A look at what chromium is — element twenty-four on the periodic table — where it sits, how it was named, and the forms it takes.

Its name comes from the Greek word for color — chrōma — for the vivid hues of the compounds it forms.

Chromium is a chemical element, number twenty-four on the periodic table: a hard, lustrous, silver-gray metal. What follows is the story of the element and its name — what it is, where it sits, and the forms it takes.

I The name

An element, named for color

Chromium is a chemical element — number twenty-four on the periodic table, a hard, lustrous, silver-gray metal. Its name is a clue to the thing that first drew attention to it: "chromium" comes from the Greek chrōma, meaning color, because the compounds it forms are so vividly colored.

It was identified at the close of the eighteenth century, drawn from a bright orange-red mineral. The metal itself is plain and steely; it is the compounds around it that carry the reds, greens, and yellows that gave the element its name.

This piece follows the element and its name — what chromium is, where it sits on the table, and the forms it takes — set within the wider study of how the body sustains itself across time.

The element

A hard, silver-gray metal

The metal itself is plain and steely — lustrous, hard, and gray — for all the color its compounds are named for.

II

The element

Chromium, in brief

A few of the plain facts about the element and its name.

The Name

"Chromium" comes from the Greek chrōma — color — for the vivid hues of its compounds.

Number 24

It is element twenty-four, with the symbol Cr, among the transition metals of the periodic table.

A Steely Metal

In its pure form it is a hard, lustrous, silver-gray metal, known for taking a bright polish.

Related Forms

In the diet it appears as trivalent chromium, in forms such as chromium picolinate and chromium chloride.

The forms

One element, several forms

Beyond the pure metal, chromium appears in a handful of chemical forms, each a different pairing of the same element.

The plain facts about the element and its name, from root to related forms:

01
Named for Color
"Chromium" comes from the Greek chrōma — color — for the vivid hues of its compounds.
02
Element Twenty-Four
It sits at number 24 on the periodic table, with the symbol Cr.
03
A Transition Metal
It belongs to the transition metals — hard, lustrous, and silver-gray.
04
Drawn from a Colored Mineral
It was identified at the close of the eighteenth century, from a bright orange-red mineral.
05
Trivalent in the Diet
In foods it appears as trivalent chromium, the +3 form of the element.
06
A Family of Forms
It appears in forms such as chromium picolinate and chromium chloride.

In the literature

A much-studied element

Chromium — the element named from the Greek for color, its place among the transition metals, and its trivalent forms — has been examined widely across the scientific literature. The discussion is broad and ongoing, and much of it remains open rather than settled.

The name

An element, and its name

Chromium is, in the end, a chemical element with a telling name — chrōma, the Greek for color, marking the vivid compounds that first drew the eye. It is one element among many found in the living world and in food, described here by its chemistry and its history alone.

A steely element that makes bright compounds — chrōma, the Greek beneath the name.

In closing

Named for color

Read back to its root, chromium is an element that wears its origin in its name — chrōma, the Greek for color, for the vivid reds and greens and yellows of its compounds. It is element twenty-four, a hard silver-gray transition metal, appearing in the diet as trivalent chromium and in a family of related forms.

None of it is a secret, and none of it is a promise. It is simply what the element is, and where its name comes from — one entry on the periodic table set within the wider story of how the body sustains itself across time.
