This percent ionic character calculator takes the figures you already have and applies the relationship behind percent ionic character calculations for you, giving difference in electronegativity (δχ), ionic character percentage and calculated moment from charge, bond length, ele charge, χ1 and χ2.
What Is the Percent Ionic Character Calculator?
The percent ionic character calculator turns charge, bond length, ele charge, χ1 and χ2 into difference in electronegativity (δχ), ionic character percentage and calculated moment.
It is a quick way to get from the numbers you have to the number you need, without setting up a spreadsheet or reaching for a formula.
How the Percent Ionic Character Works
Each result follows from the ones before it, and the calculator shows every step, so a surprising answer can be traced back to the input that caused it.
Round your inputs to the precision you actually know, and keep more precision than that in the intermediate steps.
Getting a Result You Can Trust
Run the calculation twice with slightly different inputs. A sensible calculator moves its output in proportion; a wild change points to a unit or a decimal point problem in what you entered.
Write the inputs down next to the answer. It takes a moment and it is the difference between a number you can explain and one you cannot.
A Worked Example
Working through an example, with charge set to 10, bond length set to 5, ele charge set to 2, the calculator returns difference in electronegativity (δχ) of 90, and calculated moment of 100, and ionic character percentage of 1. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out difference in electronegativity (δχ)?
Enter charge, bond length, ele charge, χ1 and χ2. The calculator then works through the relationship and reports difference in electronegativity (δχ), ionic character percentage and calculated moment.
What does the percent ionic character actually calculate?
It takes charge, bond length, ele charge, χ1 and χ2 and converts them into difference in electronegativity (δχ), ionic character percentage and calculated moment using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter charge?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Is the answer exact?
It is as exact as the formula and the inputs allow. The method itself is the standard one for this problem, so the only sources of error are the figures you enter and the precision you ask for.
Does anything you type get stored?
No. The whole calculation runs inside your browser, and nothing you enter is uploaded, logged or sent anywhere.
