Question

What can you conclude about the classification of krypton? A) Krypton is a metal and has full core electron shells, is highly chemically reactive, and located on the right. B) Krypton is a noble gas and has a full valence electron shell, is chemically non-reactive, and located in group 8A. C) Krypton is a nonmetal and has a nearly full valence electron shell, is chemically reactive, and located by group 18. D) Krypton is a metalloid and has half-full core and valence electron shells, is chemically non-reactive, and located in group 10.

Answer 1

Answer:Krypton is a noble gas and has a full valence electron shell, is chemically non-reactive, and located in group 8A

Explanation:krypton are element of group 18(VIIIA) and are refer to as noble gases because they often dont react with other gases. They are in active gases usually not found in large quantity like other elements such as Nitrogen,oxygen...It has six Isotopes/other forms and can be used for filling lamps.
