Solid or liquid argon have greater density? [44], Since 2002, the American National Archives stores important national documents such as the Declaration of Independence and the Constitution within argon-filled cases to inhibit their degradation. The remaining oxygen was reacted with alkaline pyrogallate to leave behind an apparently non-reactive gas which they called argon. Now, this is not drawn to scale as 5.5 times 10 to the third power should be hired in this axis. Argon (Ar).Argon has 18 protons as shown by the periodic Text The Royal Society of Chemistry 1999-2011 A higher recycling rate may reduce risk to supply. Argon is also used in fluorescent glow starters. We have 77.3. The bulk of argon applications arise simply because it is inert and relatively cheap. Note that it has a VERY narrow temperature range f. It is in group 18 of the periodic table and is a noble gas. [38], Argon is sometimes used for extinguishing fires where valuable equipment may be damaged by water or foam.[39].
