A list of ionsdecreasingincreasing ionic radius - EdwinCig - 01-17-2020
AlrightI have a few things I need to do, and I\'m not sure how to go about doing themthat\'s why I\'m here! Your help would be appreciated :]First thing I\'m supposed to do is figure out whether the following list is in order of increasing or decreasing ionic radiusHow would I know? If you could tell me how that\'d be great :]Here it is:7N^3- 8O^2- 9F^- 11Na^+ 12Mg^2+ 13Al^3+And I\'m also supposed to figure out the number of electrons in each of the ions aboveHow do I do that? Chemistry is not my forteeheh ~_~Best answer to whomever :]the more shells the wider the radiusso first write out the electronic configuration for each so that is : nitrogen - 2:5.7 electrons .oxygen - 2:6.8 electrons sodium 2:8:1.11 electronsmagnesium - 2:8:2.12 electrons aluminium - 2:8:3.13 electronsin the order of smallest radius to largest radius is: nitrogen ,oxygen,sodium,magnesium,aluminiumOther related question
