beacause of n to pi antibonding tranition.
Due to strong dipole dipole interaction
Chromium is a metal and, like most metals, it's a sort of shiny gray color ("silvery"). Chromium compounds can be most any color: red, orange, yellow, green, blue, and violet chromium compounds are all known. The color depends on the oxidation state of the chromium and also on what ligands are present (particularly in chromium (III) compounds).
The compounds of Cobalt as CoCl2 and Cu2O are red.
It would be yellow. Yellow surfaces only reflect yellow, light makes everything that is white or its own color the color of the light, and bananas are yellow.
Compounds of bivalent manganese are pink.
Strontium compounds provide red color (and is often found in road flares as well). Calcium compounds produce orange. Charcoal (carbon) or a mixture of iron and carbon provide the gold/yellow color. Sodium compounds produce a yellow color. Barium compounds produce green. Copper compounds produce blue. A mixture of strontium (red) compounds and copper (blue) compounds produces purple. Silver/white can be produced by: aluminum, magnesium, titanium, or antimony (III) sulfide.
Pale yellow
The chromate ion (CrO4-2) has yellow colour so all the chromate compounds including silver chromate is yellow in colour.
Due to strong dipole dipole interaction
Orange;)
Yes it is. It refers to chemicals related to xanthic acid (organic sulfur compound), or to the characteristic yellow color of related compounds.
In a flame test, potassium and its compounds emit a lilac color, which may be masked by the strong yellow emission of sodium if it is also present. Cobalt glass can be used to filter out the yellow sodium color. The potassium ion is colorless in water.

All sodium salts will give a yellow flame test, because of the metal sodium in the compounds.
Because important is the metal - sodium - and his most important spectral lines - yellow region.
Rafa's favorite color is yellow.
