The image shows a periodic table extract with the [[electronegativity]] values of metals.<ref>{{cite book |last1=Aylward |first1=G |last2=Findlay |first2=T |last3= |first3=| date=2008 |title=SI Chemical Data |edition=6|location= Milton, Queensland|publisher= John Wiley & Sons|page= 126|isbn=978-0-470-81638-7}}</ref>

{{legend inline|white}} electropositive metals with values between 1.4 and 1.9; and<br>
{{legend inline|#99CCFF}} electronegative metals with values between 1.9 and 2.54.

From the image, the group 1–2 metals and the [[lanthanide]]s and [[actinide]]s are very electropositive to electropositive; the [[transition metal]]s in groups 3 to 12 are very electropositive to electronegative; and the [[post-transition metal]]s are electropositive to electronegative. The [[noble metal]]s, inside the dashed border (as a subset of the transition metals) are very electronegative.
