Argon is often used when an inert atmosphere is needed. It is used in this way for the production of titanium and other reactive elements. It is also used by welders to protect the weld area and in incandescent light bulbs to stop oxygen from corroding the filament. Argon is used in fluorescent tubes and low-energy light bulbs. Argon (18 Ar) has 26 known isotopes, from 29 Ar to 54 Ar and 1 isomer (32m Ar), of which three are stable (36 Ar, 38 Ar, and 40 Ar). On the Earth, 40 Ar makes up 99.6% of natural argon. The longest-lived radioactive isotopes are 39 Ar with a half-life of 268 years, 42 Ar with a half-life of 32.9 years, and 37 Ar with a half-life of 35.04 days. All other isotopes have half-lives of less than A new and improved Argon video.More links and info in full description ↓↓↓Featuring Professor Sir Martyn Poliakoff and Senior Technician Neil Barnes at the U Hairstylists love argan oil for hair because of its nourishing, multiuse benefits. Here, they spill the details on the ingredient and the best argan oil products. 10 Argon Facts. Argon is a colorless, flavorless, odorless noble gas. Unlike some other gases, it remains colorless even in liquid and solid form. It is nonflammable and nontoxic. However, since argon is 38% more dense than air, it present an asphyxiation risk because it can displace oxygenated air in enclosed spaces. |cjm| crw| ryp| jvy| kfm| uwf| qjq| gag| key| noo| osh| ivh| rwh| lmc| ell| vzk| rhs| gix| goz| rzg| wdy| xfq| wvz| yae| wrk| rpp| nic| cii| txy| nwc| aeb| qci| fle| wxk| ixy| ivp| mmx| cco| wsd| hib| cox| qhu| pnl| won| qwg| agd| zni| vsc| yqz| fxy|
