![]() ![]() To remember the order of electronegativity of atoms, use the mnemonic “FONClBrISCH.” The atoms in the mnemonic are listed in decreasing order of electronegativity so F>O>N>Cl>Br>I>S>C≈H. The result of this hogging is called induction, which occurs when partial charges appear on atoms as a result of a highly electronegative atom taking electrons. When an electronegative atom like fluorine is next to a less electronegative atom, the more electronegative atom tends to hog or take some of the electrons. Therefore, fluorine (shown on the periodic table above) is the most electronegative atom on the periodic table. Electronegativity increases as you go to the right and up on the periodic table. If an atom is highly electronegative, it will try to take electrons from its less electronegative neighbors. What is electronegativity? Electronegativity is how much an atom desires electrons. Specifically, we will discuss “what is electronegativity?” and the atomic size trend. You likely first learned trends of the periodic table in general chemistry, but let’s refresh now. Trends of the periodic table are a foundational concept of organic chemistry. ![]()
