Welcome to this video on radicals.<\/p>\n<p>Within chemistry, the term <em>radical<\/em> (more commonly called a free radical), refers to an atom, <a class=\"ylist\" href=\"https:\/\/www.mometrix.com\/academy\/molecules\/\">molecule<\/a>, or ion that has one or more unpaired valence electrons that are covalently bonded.<\/p>\n<p>Though there are some outliers, because of the unpaired electrons, free radicals become extremely reactive with other substances and with themselves.<\/p>\n<p>Free radicals can often cause a chain reaction. This is because when one free radical searches to bond with another unpaired valence electron which regenerates a new radical causing a domino effect of reactions. Propagation phase is the term used to describe this series of reactions.<\/p>\n<p>Radicals can detach hydrogen or other atoms from several different solvents and reagents; this is seen in a group transfer reaction (&#8220;transfer reaction&#8221; meaning the transfer of an atom or group of atoms from one molecule to another).<\/p>\n<p>In general, most free radicals that occur organically have very short lifespans and disproportionate (this is a group transfer into dissimilar molecules) or dimerize (meaning that an atom or atoms are transferred to similar molecules), and these reactions happen at a very specific diffusion controlled rate. Diffusion controlled rate means that they react at the moment of contact.<\/p>\n<p>Free radicals are a very important, specific, and intricate part of chemistry that can oftentimes be hard to understand.<\/p>\n<p>I hope this video was helpful! Thanks for watching, and see you next time!<\/p>\n<\/div>\n<\/div>\n\n<div class=\"home-buttons\">\n<p><a href=\"https:\/\/www.mometrix.com\/academy\/safety-professional\/\">Return to Safety Professional Videos<\/a><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Return to Safety Professional Videos<\/p>\n","protected":false},"author":1,"featured_media":91072,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":{"0":"post-34521","1":"page","2":"type-page","3":"status-publish","4":"has-post-thumbnail","6":"page_category-safety-professional-videos","7":"page_category-video-pages-for-study-course-sidebar-ad","8":"page_type-video","9":"subject_matter-business-finance"},"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO Pro 4.9.9 - aioseo.com -->\n\t<meta name=\"description\" content=\"Highly reactive free radicals can cause a chain reaction.
