Question

compared to molybdenum and tungsten and chromium does not have an extensive polyanion chemistry. suggest an explanation​

Answer 1

Explanation:

The physical and chemical characteristics of chromium and some of its compounds are summarized.

The physical and chemical characteristics of chromium and some of its compounds are summarized.The term chromium is derived from the Greek word for color, because most chromium compounds are brightly pigmented. The element chromium was discovered in 1798 by N. L. Vauquelin, but it had already been used in swords by the Hittits about 1300 B.C. Chromium occurs in nature in bound‐form chromite ore, which is the only chromium ore of any importance, and it makes up 0.1–0.3 ppm of the earth's crust. The red color of rubies and green color of emeralds, serpentine, and chrome mica are produced by chromium.

The red color of rubies and green color of emeralds, serpentine, and chrome mica are produced by chromium.Chromium metal is prepared by reducing the ore in a blast furnace with carbon (coke) or silicon to form an alloy of chromium and iron called ferrochrome, which is used as the starting material for the many iron‐containing alloys that employ chromium.
