Question

we cannot keep sodium metal on our palm but we can eat sodium in the form of ion ...how???

Answer 1

Na in its element form is quite highly reactive because it contain 1 electorn in itsoutermost shell and is wanting to be stable by achieving an octate and the electronic configuration of neon which is 2,8. but when it is in its compound form like nacl, it has formed its octate and has achieved the electronic configuration of neon so it will no longer react (unless wemake it react).

So, Na cannot be kept on hand but NaCl can be eaten...

Answer 2

Hiiii friend!!

Here is your answer

As we know that the electronic configuration of sodium is 2,8,1 it is highly reactive (because it needs to loose only one electron to complete its octet and get the electronic configuration of neon) but when it forms the compound sodium chloride it loses one electron and hence reaches to the noble gas configuration and hence when it is eaten or kept on the palms it does not react. Same is the case with chlorine too. It has a very pungent and suffocating smell but if you smell the sodium chloride (common salt) do you feel like fainting? No. While forming the compound sodium chloride, it accepts the electron from sodium and gets the configuration of the noble gas Argon (2,8,8), hence forming the compound NaCl.

Hope this helps you friend...
