Krypton (Kr) and bromine (Br) are Period 4 elements that are also called p-block elements. Krypton is a noble gas while bromine is a halogen.
While comparing the stability of the two elements, Krypton is more stable than bromine. This is because being a noble gas, Krypton follows the octet rule and maintains its stability. Bromine has 35 electrons and the outer most valence shell has 7 electrons so its unstable. Krypton has 36 electrons and 8 electrons in the valence shell so its stable.
Morphological Traits: changes to the outward appearance of an animal as well as the form and structure of internal parts, like bones and organs. Example: Snowshoe hare is more than prepared for the winter environment with large back feet for easy travel and a white
coat for camouflage.
