valence electron造句
1. In molecules with unpaired valence electrons, spin-spin coupling between valence and core electrons leads to further small splittings.
2. Chlorine has a high valence electron energy.
3. These have low average valence electron energies.
4. Elements 3 is a nonmetal with one valence electron.
5. So then, I could say that the average valence electron energy for oxygen would then be, I've got two s electrons.
6. Its average valence electron energy is 5.2 electron volts, which is a heck of a lot less than 11.
7. 0eV This is almost 20 eV, high average valence electron energy, greater than 13 electron volts.
8. Thus in the depth of the valence electron theory of solid solution the mechanical behavior of the alloy elements in martensite was shown.
9. All right, well, oxygen has the highest valence electron energy.
10. OK, elements with low average valence electron energy, and here I'm saying below 11 electron volts, these are good electron donors.
11. By calculating the number of valence electron shell, we can gain the geometry array of the electronic pair, and then judge the molecular structures.
12. Bonding may be ionic or covalent, depending on whether valence electrons are transferred or shared.
13. Cl We know that because the sulfur and the chlorine in the oxygen have different average valence electron energies, they'll have different electron affinities.
14. And the idea is that when you do these Lewis dot structures, we're representing electrons with dots, which we'll see in a minute,[http://] and each dot is going to represent a valence electron.
15. Just to refresh our memories, we looked at the average valence electron energy as a measure of reactivity.
16. If you take a look at the last day, or the day before, you will see that we talked about average valence electron energy.
17. And we do so by a quantity called the average valence electron energy.
18. And, it says, OK, center the element with the lowest average valence electron energy.
19. Place the non-bonding pairs on peripheral atoms first, which the higher average valence electron energy.
20. The formation mechanism of Al-based amorphous alloy was summarized and it has the characteristic of valence electron concentration and the principle of similarity.
21. On the basis of the principle, the OET (orbital-energy topological index) was proposed by revising the valence electron distance matrix with the orbital energy.
22. And up in the other extreme are elements with very high average valence electron energy.
23. We have to account for that in some way because we know that they don't have identical average valence electron energies.
24. Hole - Similar to a positive charge, this is caused by the absence of a valence electron.
25. The acceptor atoms are required to have one less valence electron than the semiconductor.
