In severe cases of poison ivy, poison oak, or poison sumac, it is a good idea to see a doctor. Sometimes large blisters need to be drained and sometimes an oral steroid such as prednisone may be useful. Systemic steroids produce rapid resolution of both the itching and the rash.
Crystalline solids have a highly ordered arrangement of constituent atoms, ions or molecules in a three-dimensional layer or lattice giving rise to distinct geometrical shapes. Thee are two important types of crystalline solids. 1  Ionic solids (represented by sodium chloride).
These characteristics all describe what an amorphous solid can do. Let's look at the origin and properties of this solid. A solid is a material that has a defined shape. In chemistry, solids are referred to as states of matter that are not just defined by shape but also volume. There are two types of solids: crystalline and amorphous solids. Think of these as the odd couple, they are complete opposites. Crystalline solids have long-range order as their structure is very defined and carries a distinct pattern.
