Electronegativity values from thermochemical data
TL;DR: In this paper, the electronegativities of sixtynine elements have been calculated from the most recent thermochemical data, and the mean deviation of the calculated electronegativity difference, 0·208 √ †, from the difference of the average electrone-gativities is 0·046 units.

Chemical bonding in bismuth telluride
J.R. Drabble,C.H.L. Goodman +1 more
TL;DR: In this paper, a model for the chemical bondins in bismuth telluride is proposed, which appears to dispose of some of the difficulties involved in earlier models, and is used to explain some properties of BTE and its alloys with BTE.
