Galvani's frog united chemistry, physics. THE UNION of physics and chemistry began with the twitching of a frog's leg. In the 1790s Luigi Galvani lay a dead frog on a table. Also on the table was a static electricity generator. An assistant accidentally touched the nerves of the frog with a scalpel and the muscles of the frog contracted . Chemistry. What are Halogens?. Halogens are a series of non-metal elements located in group 7 of the periodic table. The term “halogen” means. “salt. -former”.. . All halogens . have seven electrons in their outermost. Chemical Equations. This equation means:. 4 Al(. s. ) + 3 O. 2. (. g. ) 2 Al. 2. O. 3. (. s. ). 4 Al atoms + 3 O. 2. molecules yield 2 molecules of Al. 2. O. 3. 4 Al . moles. I. n-grade.

What are we testing to find?. Halides. are salts that contain halogens, which include chlorides, bromides and iodides.. Chlorides, bromides and iodides are negative ions - negative ions are called anions.. 1). 2). 3). 4). Group 7. Explain the trend in boiling points of Cl. 2. , .
