Krypton is named after the greek word that means “secret.” which explains why krypton was most likely given this name? krypton is a halogen, so it is a secret element because it is always part of a compound and is difficult to find by itself. krypton is a halogen, so it should be kept secret because it is so reactive and toxic. krypton is a noble gas, so it was difficult for chemists to find it, as though it was a secret. krypton is a noble gas, so it secretly bonds with every type of element without showing it.

Krypton is a noble gas, so it was difficult for chemists to find it, as though it was a secret

Explanation:

Krypton  is a noble gas and this demand it has full orbital electron shells (2.8.18.8 or [Ar].3d¹⁰.4s².4p⁶). They, therefore, do not have an affinity for gaining or losing an electron hence rarely react with other elements. They were therefore hard to discover by early chemists because there were no known compounds of this gas and other noble gases. This is why the name ‘hidden’.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

ya the other dude is right
