To find the value, ions are treated as if they were hard spheres. The size of an element's ionic radius follows a predictable trend on the periodic table. As you move down a column or group, the ionic radius increases. This is because each row adds a new electron shell. WebShell 1: 2 electrons. Shell 2: 8 electrons. Shell 3: 18 electrons. Shell 4: 32 electrons. Shells 5 through 7: 32 electrons in any known element, however there are additional orbitals available to hold even more electrons, but there is no element with a large enough atomic number to fill up those slots.
