if sodium is in a compound, it will not be in natural state. natural state implies that it is a pure element. ie not a compound
Sodium (Na) is a highly reactive element so it cannot be found in free state but we can have it in compound form like NaCl.
Silvery white
Sodium Bromide
Sodium is highly reactive and never exists in free state. It is always found in the combined state.
Since sodium is quite reactive it is always found in chemical combination with one or more other elements, most commonly chlorine. This is sodium chloride, the principal ingredient in common table salt.
solid
yes, the natural state is metal.
Sodium chloride is a compound which is a solid at room temperature.
Bromine is in +5 oxidation state, oxygen is -2 and sodium is +1.
Natural gas is a gas.
Sodium has +1 in every compound. It has zero number in pure state.
The symbol (aq) is used to denote that sodium chloride (or any other compound) is in aqueous medium.
