Krypton is a part of the family of elements known as the noble gases. They all lack odor and color, and they are barely reactive.
Krypton (Kr) is the neutral element with 36 electrons, but there are ions (elements that have lost or gained electrons) that can have 36 electrons as well. This includes arsenic, selenium, bromine, rubidium, strontium, yttrium, zirconium, niobium, molybdenum, technetium, ruthenium, rhodium, palladium, silver, cadmium, and indium.
Noble gases include Neon, Argon, Krypton, Xenon, Radon, Helium, and ununoctium.

Fluorine even combines with argon, krypton, xenon, and radon. Even in dark, cool conditions, fluorine reacts explosively with hydrogen. http://en.wikipedia.org/wiki/Fluorine Fluorine even combines with argon, krypton, xenon, and radon.

Sodium is the most reactive.
Rubidium
Yes
Neither. Both argon and krypton does not react with nitrogen.
arsenic associates with phosphorus
No. It is very reactive
Arsenic.
Krypton is not reactive and be mixed with any gas.
Non-reactive, along with all other noble gasses.
slicon of course
Arsenic is not highly reactive, because it is unaffected by air, water, and most acids and alkalis.
Noble gasses are least reactive of all the elements. So the least reactive element in the period 4 is Krypton. It is a noble gas with an atomic number of 36.
