About the accents: This is not a mistake, it is on purpose. Please note that in Spanish some words have accents when asked in a question (I.e que, porque, qui...). Pay attention to the question mark.

Krypton belongs to the family known as the noble gases. This family also includes helium, neon, argon, xenon and radon. All are considered nonreactive, nonmetallic elements and have eight valence electrons.
Under normal conditions krypton is colourless, odourless, fairly expensive gas. Solid krypton is a white crystalline substance with a face-centered cubic structure which is common to all the rare gases. Krypton difluoride, KrF 2, has been prepared in gram quantities and can be made by several methods.
