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.
Like the other noble or inert gases, helium (He), argon (Ar) and radon (Rn), Neon, Krypton and Xenon remain in the air because they do not combine with other materials to form solid or liquid compounds. All of these gases are monatomic. Neon, Krypton and Xenon are valued for their light emitting properties when electrically charged. Krypton and Xenon are also valued for their total inertness coupled with high molecular weight (83.80 and 131.30, respectively).
