Manganese. Transition metal ions exhibit electron transitions between their electron orbitals which absorb light of certain wavelengths, making the compound coloured.
Manganese nitrate typically appears as a colorless or pale pink solid. Its exact color may vary slightly depending on the specific formulation and purity of the compound.
Copper (II) nitrate burns with a blue-green flame, characteristic of copper compounds.
White
Iron(II) nitrate is typically a greenish compound.
Silver nitrate appears as colorless or white crystals.
Colours of the hair of different people differ due to presence of transition elements in them. Brown colour of hair is due to the presence of compounds of iron (Fe), cobalt (Co) and copper (Cu), whereas molybdenum (Mo) compounds impart red colour and titanium compounds give ginger colour to the hair.
the colour of Manganese is silvery metallic.
lead oxide
Copper Nitrate or Cu(NO3)2 is blue in colour.
white powder and colourless crystals.
metalicc or grey
When an apple is heated, the heat breaks down the cell structure and compounds responsible for color in the skin, causing it to change color. This is due to the breakdown of chlorophyll, which is responsible for the green color, and the formation of new compounds that impart a different color to the apple skin.
