electronegative elements造句

例句与造句

1. It is the most electronegative element and elemental fluorine is a strong oxidant.
2. NCI can be used for the analysis of compounds containing acidic groups or electronegative elements ( especially halogens ).
3. BF is unusual in that the dipole moment is inverted with fluorine having a positive charge even though it is the more electronegative element.
4. Both contain fluorine, the most electronegative element, but only NaF dissolves in water to form separate ions, Na + and F -.
5. Highly electronegative elements, e . g ., halogens, are favored as they rapidly recombine with the ions present in the discharge channel.
6. It's difficult to find electronegative elements in a sentence. 用electronegative elements造句挺难的
7. Oxygen is the most electronegative element except for fluorine, and forms compounds with almost all of the chemical elements, including some of the noble gases.
8. When formal charges are necessary, resonance structures that have negative charges on the more electronegative elements and positive charges on the less electronegative elements are favored.
9. When formal charges are necessary, resonance structures that have negative charges on the more electronegative elements and positive charges on the less electronegative elements are favored.
10. For example, nitrogen, sulfur and chlorine are strongly electronegative elements, and therefore nitric acid, sulfuric acid, and perchloric acid, are strong acids.
11. The familiar Allen electronegativity scale, which relies only upon ( measurable ) atomic energies, identifies neon as the most electronegative element, closely followed by fluorine and helium.
12. The reason for this is because N been an electronegative element, when combined with H will result in gaining a partial negative charge and H will get a partial positive charge.
13. Oxygen primary ions are often used to investigate electropositive elements due to an increase of the generation probability of positive secondary ions, while caesium primary ions often are used when electronegative elements are being investigated.
14. The  " 1 occurs because each C is bonded to one hydrogen atom ( a less electronegative element ), and the  " because the total ionic charge of  " 1 is divided among five equivalent C.
15. Hence, the outermost electrons are subject to a shielding effect from the inner electrons that makes them more easily electronegative elements, fluorine and oxygen, and even with less electronegative elements such as nitrogen and carbon under certain circumstances.
16. Hence, the outermost electrons are subject to a shielding effect from the inner electrons that makes them more easily electronegative elements, fluorine and oxygen, and even with less electronegative elements such as nitrogen and carbon under certain circumstances.
