Question

What are the three primary components of IT?

Answer 1

Unfortunately, your question isn't very clear. "IT" usually means information technology, the primary components of which include hardware, software, telecommunications, data sources, and web-based technologies. But since you asked this in the Chemistry section, you probably don't mean information technology. At the same time, it's not possible to determine what you do mean. Perhaps you mean intervalence transition, which is when light of a certain frequency strikes a crystal, causing an electron to move from one ion to a different ion in the crystal structure, resulting in a change in energy level and the emission of light with a characteristic color. This process is responsible for the color of some gemstones, including sapphire and aquamarine.
