Why is one resonance structure a larger/smaller contributor than another - because it is lower/higher energy than another - e.g more/less stable than another. "It" referring to the resonance structure as if it were an isolated, existing structure, which in reality it is not. $\endgroup$ – ron Jul 16 '15 at 19:04
Nov 15, 2018 · Resonance structures are all of the possible different Lewis structures that a molecule might have. Calculating the formal charge for a molecule allows you to determine which resonance structure is more likely to be the molecule’s correct structure, and the Lewis structure which is considered the most correct will be the structure that has ...

Resonance. In light of computational chemistry, a better treatment would be to invoke sigma bond resonance in addition to hybridisation, which implies that each resonance structure has its own hybridisation scheme. All resonance structures must obey the octet rule.
The resonance frequency of RF MEMS can be, depending on its design, highly sensitive to mechanical stress - from the package, for example. Acoustic coupling is a well-known effect, where the resonating of one device affects a nearby device.
When the Lewis structure of an ion is written, the entire structure is placed in brackets, and the charge is written as a superscript on the upper right, outside of the brackets. For example, consider the ammonium ion, NH 4 + , which contains 9 (5 from N and 1 from each of the four H atoms) –1 = 8 electrons.
Resonance structures are imaginary. They represent extremes of electron location. Resonance can be considered as a valence theory solution to a molecular orbital problem. In general chemistry the concept of resonance was introduced through inorganic anions such as NO3-, NO2-, ClO4-, SO4-2...
