Chemical Bonding : Polarity I: Electronegativity Quiz

Quiz
*Theme/Title:	Polarity I: Electronegativity
* Description/Instructions
Electronegativity is the tendency of an atom to attract electrons. The character and type of chemical bond can be predicted using electronegativity differences. For instance, fluorine's electronegativity is 3.98 and lithium's is .98. The difference between their electronegativities is 3.00. For identical atoms, the electronegativity difference is 0.0, which results in a nonpolar covalent bond. Unequal sharing of electrons results in a polar covalent bond. Large differences in electronegativity indicate electron transfer, which means that the bond formed is ionic. The above example with lithium and fluorine has a large electronegativity difference, which means that the bond formed between them is ionic. An electronegativity difference of 1.70 is considered to be half ionic and half covalent. Anything greater than 1.70 is ionic and anything less than 1.70 is covalent. This quiz covers the basics of polarity using electronegativity values. You will need to refer to the attached chart of electronegativities to complete this quiz. Please select the best answer from the given choices. For convenience, electronegativity is abbreviated as e-neg.
