can you share the colors and identification of different important elemnts in chemistry
All Alkali Metals are silver in colour.
In the Alkaline Earth metals Group, all of them are also silver, except for Magnesium and Beryllium, which are gray, and Strontium, which is yellow-ish.
You do not need to know about the Rare Earth Metals.
Tin is white, Aluminium is silver, Iron is also silver, Nickel is white, Copper is reddish-orange/brown, Zinc is silver, Silver is silver (le gasp :p), Gold is gold (Hallelujah), Mercury is silver, Boron is brown, Sulfur is yellow, Hydrogen and Nitrogen and Oxygen is colorless, Carbon is black, Phosphorus is white.
All Noble Gases are colorless.
Fluorine is pale yellow, Chlorine is green, Bromine is reddish-brown, and Iodine is blackish-purple.

You do not need to know all of the above elements, but only the important ones like the Alkali Metals, Iron, Copper, Aluminium, Magnesium, Calcium, Sulfur, Hydrogen, Oxygen and Carbon.

Ion identification:

You will find any ion identification sheet at the back of every practical paper of Chemistry (Paper 5).

Tell me if you need anything else ;)
