Webvalence, also spelled valency, in chemistry, the property of an element that determines the number of other atoms with which an atom of the element can combine. Introduced in 1868, the term is used to express both the power of combination of an element in general and the numerical value of the power of combination. WebThe X-ray absorption fine structure (XAFS) was sensitive to the valence of elements, which was examined to explore the possible change of the state of Sn in the SnO 2 films (SnO and SnO 2 powders as the references). As shown in Fig. 1 a, b, the two peaks before the white lines in the spectra belonged to the 2p 3/2-5 s 1/2 transition [29].Although the Sn element …
