are noble gases toxic
The Noble Gases The elements of Group VIII of the Periodic Table are gases which have closed shells and are unreactive chemically. Helium, neon, argon and krypton are used in gas discharge decorative ligthing, called neon lights. Group VIIIA (new Group 18) are called the noble gases. They used to be called the inert gases, but Neil Bartlett at UC, Berkeley showed that the noble gases could be made into compounds. Their reactivity is minimal. The noble gases are; Helium, Neon, Argon, Krypton, Xenon, and Radon. Radon is toxic, as it is radioactive. The other elements that are gases at room temperature are: fluorine, F2; chlorine, Cl2; oxygen, O2; nitrogen, N2; and hydrogen, H2. All these gases are diatomic. The halogens, fluorine and chlorine, are highly reactive, and very toxic. Oxygen and nitrogen are reactive, or can be made to react. They are not toxic per se. Hydrogen is, of course, very reactive. Hydrogen and nitrogen are not toxic, but they will suffocate you, as would the noble gases, if you ingested pure forms of them, and your oxygen supply was quenched. Helium, atomic number 2. atomic mass 4.00 amu. most common phases is a gas. like all the noble gases. it’s non toxic, we use it in balloons. it’s lighter than air so it makes you sound like Scooby Doo. Argon. atomic number 18. atomic weight 39.948. it’s colorless and it’s odorless and it’s heavier than air. presented 1% in our atmosphere. Chorus. Noble gases . sittin on their thrown. Don’t mix with other elements The noble gases are; Helium, Neon, Argon, Krypton, Xenon, and Radon. Radon is toxic, as it is radioactive. The other elements that are gases at room temperature are: fluorine, F2; chlorine, Cl2; oxygen, O2; nitrogen, N2; and hydrogen, H2. All these gases are diatomic. Colorless, odorless, tasteless, and non toxic, as it has a very low chemical re activity. Melting point - -157.36 degrees Celsius Boiling point- -153.22 degrees Celsius Colorless, odorless, tasteless and non-toxic gas Melting point- -248.59 degrees Celsius Boiling point- -246.08 degrees Celsius Phase at room temperature: Gas Argon Denser than air 1.784 grams density Colorless, odorless, tasteless, and non-toxic under most conditions. Melting point- -189.35 degrees Celsius Boiling point- -185.85 degrees Celsius None of the noble gases are toxic, as none of them react with anything. The densities of the noble gases increase with increasing molecular mass. Helium is about one seventh the density of air and can be used in balloons and lighter-than-air craft. Xenon is about five times the density of air. Noble gases are used to advantage in environments where corrosion or damage from electrical discharges might occur if the environments were filled with air. One such use is in fluorescent light tubes. Noble gases Helium, neon, argon, krypton, xenon AND radon The Noble Gases typically have very low melting and boiling points, have a low density, are gas at room temperature, and are typically odorless, colorless, insipid and non-toxic (except for radon). They are either denser or lighter than air. Helium- Lighter than air 0.1786 grams density Melting point -272.0 °C Boiling point - 268.6 °C The Noble Gases.

Yes, Radon is a noble gas that is toxic.
