Examples: chlorides, nitrates, phosphates, chlorates, bromides, iodides etc.
Some salts are melted, other sublime, other are thermally decomposed.
Because salts are different products from the reactions between different acids and different bases.
Where ? Today millions of salts are known by chemists.
Some calcium salts are organic, some calcium salts are inorganic.
Salts are the result of acids neutralizing bases. If the base is weak and the acid is strong, the salt will have some acid character. If you dissolve an acid salt in water, it will lower the pH.
Salts have different crystalline structures.
This is not mandatory: some salts are very soluble, some salts are very insoluble.
The electrical properties of salts are very different.
Salts are the products of reactions between acids and bases.
Some salts are shiny.
All salts are crystallized.
Only some salts are insoluble.
