The upper steadiness of your wholly loaded noble gas configuration contributes to quite substantial 2nd ionisation enthalpy for sodium. Then again, Ma+ shaped immediately after shedding 1st electron even now has another electron in its outermost (3s) CBSE Class 11 Chemistry orbital. Due to this fact, the next ionisation enthalpy of magnesium is much lesser than that of sodium.
This is due to immediately after dropping an electron, sodium attains the steady noble fuel configuration. Then again, magnesium, immediately after getting rid of on electron however has a single electron.
(e) Defaecation — The expulsion of undigested remains of food within the alimentary canal is known as defaecation.
Remedy: Atomic radius. The space from the centre of nucleus towards the outermost shell o electrons during the atom of any component is known as its atomic radius. It refers to the two covalen or metallic radius based upon whether or not the aspect can be a non-metal or perhaps a metal.
