Krypton compared to other anaesthetic gases (minimum alveolar concentration is an inverse indicator of potency) Krypton is considered to be a non-toxic asphyxiant. ...
Kryptonite is a fictional material that appears primarily in Superman stories published by DC Comics.In its best-known form, it is a green, crystalline material originating from Superman's home world of Krypton that emits a unique, poisonous radiation that can weaken and even kill Kryptonians.
Toxic gases, by contrast, cause death by other mechanisms, such as competing with oxygen on the cellular level (e.g. carbon monoxide) or directly damaging the respiratory system (e.g. phosgene). Far smaller quantities of these are deadly. Notable examples of asphyxiant gases are methane, [1] nitrogen, argon, helium, butane and propane.
Toxic in some forms; pure phosphorus is poisonous to humans. [11] platinum: 78: 2c: Has no known biological role, but it is a component of the drug cisplatin, which is highly effective in treating some forms of cancer. [11] Toxic in some forms. Contact can promote an allergic reaction in humans. [11] plutonium: 94: 1bc
For instance, argon, krypton, and xenon form clathrates with hydroquinone, but helium and neon do not because they are too small or insufficiently polarizable to be retained. [61] Neon, argon, krypton, and xenon also form clathrate hydrates, where the noble gas is trapped in ice. [62] An endohedral fullerene compound containing a noble gas atom
A crystalline material, originally in various colors with separate effects, harmful to Kryptonians and created during the destruction of Superman's home planet Krypton; synthesis is also possible. John Byrne 's retcon of the DC Comics universe established green kryptonite as a compound and later issues had experiments by Batman and Luthor ...

A period 4 element is one of the chemical elements in the fourth row (or period) of the periodic table of the chemical elements.The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behaviour of the elements as their atomic number increases: a new row is begun when chemical behaviour begins to repeat, meaning that elements with similar behaviour fall ...
