Xenon light bulb is described as light bulb which is made from xenon. They are known to last up to 10,000 hours. Xenon bulbs can be touched with a bare hand unlike halogen bulbs. They are commonly used in path lighting. Two (2) types of xenon light bulbs are the festoon bulbs and LED.

XPS is the acronym of X-ray photoelectron spectroscopy. It also refers to extruded polystyrene.

XX is a Roman number and stands for 20 (twenty).

Xanthates are formed by combining alcohol with carbon disulfide in the presence of an alkali metal - namely lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), or francium (Fr).

X-ray photoelectron spectroscopy (XPS) is a surface sensitive analytic tool used to study the surface composition and electronic state of a sample.

Xylenol is characterized as an arene compound with two methyl groups and a hydroxyl group. 6 isomers exist of xylenol of which 2,6-xylenol with both methyl group in an ortho position with respect to the hydroxyl group is the most important.

X- Ray diffraction is a tool for the investigation of the fine structure of matter. This technique had its beginning in von Laue's' discovery in 1912 that crystals diffract x-rays, the manner of the diffraction revealing the structure of the crystal.

X-Ray refers to the part of the electromagnetic spectrum whose radiation has somewhat greater frequencies and smaller wavelengths than those of ultraviolet radiation; namely, that radiation lying between ultraviolet and gamma-ray in the electromagnetic spectrum.
