Report Abuse. X-radiation (composed of X-rays) is a form of electromagnetic radiation. X-rays have a wavelength in the range of 0.01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3 Ã 1016 Hz to 3 Ã 1019 Hz) and energies in the range 120 eV to 120 keV.hen x-rays were first discovered, scientists didn't know much about them, so they called them X-rays because X in science is often used to designate an unknown as in Planet X or solve for X They were also sometimes called Rontgen Rays after the man who discovered them.

Conclusion. Calcium chloride is an important salt, both commercially and naturally. As with all salts, calcium chloride is composed of ions bonded through ionic bonds. The properties of this salt allows us to utilize it for multiple purposes, including food production, construction, and medicinal uses.alts are inorganic compounds composed of ions, or charged particles. These ions include positively charged ions, called cations, and negatively charged ions, called anions. These compounds form through ionic bonds, which are bonds that developed based on opposite charges attracting each other.
