2.A reaction in which the atoms of an element lose electrons and the valence of the element is correspondingly increased. [French, fromoxider,to oxidize, fromoxide,oxide; seeoxide.] ox′i·da′tiveadj. ox′i·da′tive·lyadv. American Heritage® Dictionary of the English Language, Fifth...
[5]). However, there have been relatively few studies on compounds in regard to stoichiometry, such as A(CN)2A(CN)2, where A is not a common +2+2 valent element (e.g., alkaline-earth metal and zinc). Therefore, it is worthwhile to investigate the potential structures of these ...
Identify the valence electrons and the orbitals in which element Cl resides. Identify the atom whose electron configuration is Ne 3s23p5. How many unpaired electrons are there in the ground state of this atom? Which ion does not have a noble gas ...
Al3S4becomes a superconductor with a predicted superconducting transition temperatureTcof 20.9 K at 100 GPa, while the pressure-induced Al2S becomes an electride, where the valence electrons of aluminum strongly localize in the interstices, acting as anions, at a pressure of 70 GPa. This...
The removal of a second electron results in a cation with a +2 charge. The energies involved are called the first and second ionization energies of the element respectively. Valence electrons will always be removed first, with significantly more energy required to remove core...
Dalton attributed to the atoms “atomic weight,” that is, a specific mass which was characteristic of each chemical element. The measure of a chemical element that represented the unity of its qualitative aspect (its chemical individuality) and its quantitative aspect (the value of its “atomic...
