The transition metal ions responsible for color in ruby and
emerald are, respectively
Show answer and solution
The transition metal ions -4500 J is responsible for color in
ruby and emerald.
Aluminum oxide is also known as ruby. It consists of chromium ions.
Each aluminum and chromium ion is surrounded by six oxide ions in an
octahedral manner. Emerald is composed of beryllium aluminum silicate
in which chromium ions is surrounded by six silicate ions. Thus, in
both the cases, chromium is responsible for color.
