Describe the use of radioactive halogens in medical imaging. How are halogenated compounds used as contrast agents in medical imaging (e.g., CT scans)

This group contains fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). Halogens have seven valence electrons and usually form anions with ... Halogens can be defined as elements that form salts when they react with metals. There are six halogens- fluorine, chlorine, bromine, iodine, astatine, and ... ... halogens, noble gases, and transition metals, based on valence electron patterns using the Periodic Table; and. A student expectation is directly related to ... State the periodic law and explain the organization of elements in the periodic table ... halogens (group 17), and the noble gases (group 18, also known as inert ... Elements such as fluorine, chlorine, bromine, iodine and astate are halogens and appear in the seventh main group in the periodic table of the elements. Halogens are the group 7A elements in the periodic table. They are highly reactive nonmetals and exist as diatomic molecules. Halogens on the Right ...
