What is the most volatile element?

Characteristics. Francium is one of the most unstable of the naturally occurring elements: its longest-lived isotope, francium-223, has a half-life of only 22 minutes.

Which elements are volatile?

Volatiles include nitrogen, carbon dioxide, ammonia, hydrogen, methane, sulfur dioxide, water and others.

Which is the most volatile compound?

Volatility is tendency of a substance to evaporate at normal temperatures. Here 2, 2-dimethyl propane has the least surface area. Thus, van der Waals force of attraction between the molecules is less and hence, lesser amount of energy is required to move them apart. So, it is the most volatile compound among these.

Which element is extremely toxic?

Arsenic is a Classic Poison Arsenic may be the element best-known as a poison. People have been poisoning themselves and each other with arsenic since the Middle Ages. In Victorian times, it was a poisoner’s obvious choice, however, people were also exposed to it as it was used in paints and wallpaper.

Is oxygen volatile?

Is oxygen a volatile or refractory element, and why? Pure oxygen is a gas at 1-atmosphere pressure and room temperature. It boils at 90 K (much lower temperature than room temperature, 300 K), and so it is very volatile.

Is memory volatile?

Volatile memory is computer storage that only maintains its data while the device is powered. Most RAM (random access memory) used for primary storage in personal computers is volatile memory. Volatile memory contrasts with non-volatile memory, which does not lose content when power is lost.

Is Hi more volatile than H2SO4?

Reason: HI is more volatile than H2SO4 29.

Which is the most volatile acid?

Acetic acid is the most acid of the volatile acids into wine, so that analytical only acetic acid is measured as volatile acid. There appear also formic acid, succinic acid, butyric acid and propionic acid in negligible amounts.

Is there an element 119?

Ununennium, also known as eka-francium or element 119, is the hypothetical chemical element with symbol Uue and atomic number 119. Ununennium and Uue are the temporary systematic IUPAC name and symbol respectively, which are used until the element is discovered, confirmed, and a permanent name is decided upon.
