Web17 aug. 2024 · Most important thing for this question is that you seem to think that data for ionic or atomic radii are for bare atom or ion which is not true. These are just calculated values for particular types of compounds. – Mithoron Aug 17, 2024 at 17:17 Show 3 more comments 1 Answer Sorted by: 1 WebWhen forming ions, elements typically gain or lose the minimum number of electrons necessary to achieve a full octet. For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge. We can use this method to predict the charges of ions in ionic compounds.

WebThe ionic radius of an element is a measure of the size of an ion Ionic radii show predictable patterns Ionic radii increase with increasing negative charge Ionic radii decrease with increasing positive charge These trends can also be explained by the electron shell theory WebThe oxygen atom has a 2− charge as an ion. To balance the positive and negative charges, we look to the least common multiple—6: two iron 3+ ions will give 6+, while three 2− oxygen ions will give 6−, thereby balancing the overall positive and negative charges. Thus, the formula for this ionic compound is Fe 2 O 3. coushatta casino resort slot updates
