Paperback. Condizione: new. Paperback. Chlorine is an atom from the family of Halogens. She is well placed to introduce the concept of the Electronegativity, Reduction, and Oxidation processes. She is in Column 17 (or Group 7A) of the Periodic Table. She has 7 "hands" or valence electrons and only one "empty sleeve" in her outermost shell. She likes to steal an electron to fill up her outer shell. You will learn that an Oxidizing Agent is an aggressive atom (or compound) that takes "hands" or valence electrons rather than give them away; a real thief! A Reducing Agent is the opposite. He/She likes to give away his/her valence electrons (as the atoms in Columns 1 and 2 (Groups 1A and 2A) from the Periodic Table). Atoms in Groups 1A and 2A have low electronegativity. Halogens (Group 7A) have a large electronegativity (close to 4). This item is printed on demand.
