Electronegativity values

[Sophia_Kiessling_2L]

Will we be given values of electronegativities when asked, for example, to say which compound would have bonds that are primarily ionic?

[Andre_Galenchik_2L]

Most likely, as we do not need to memorize each element's value, but rather the trend across a group and period.

[Marwan Masri 3B]

yes, you'll be provided with the electronegativities needed to answer such a question, eventhough you could probably make a pretty accurate guess based on whether the elements are metals/nonmetals and such.

[KatelinTanjuaquio 1L]

We should be given the electronegativities as we are usually not asked to memorize values.

If it were on a test I'd imagine the electronegativity values would be given to each element listed because between 1.5 to 2 the molecule tends to have some covalent character, and to figure out that precise value some number would be given to us I'd imagine. So I wouldn't worry about it too much but have a general sense of what molecules are covalent and ionic bonds. Ionic bonds are usually salts like KCl, KF, LiF and covalent bonds are molecules such as Hi, HBr, HCl.
