Question

show diagrammaticaly the electron distributions in a sodium atom was and a sodium ion and also give their atomic no.​

Answer 1

Answer:

Atomic number of sodium (Z) = 11 Mass number of sodium (A) = 23 Number of protons in the nucleus = 11 Number of neutrons in the nucleus = 23 - 11 = 12 Number of electrons = 11 Electronic configuration of Na atom Na+ ion is formed from sodium atom by loss of an electron (present in the outermost shell).

please like me

Answer 2

Answer:

sodium has 11electrins

therefore electronic configuration is.. 1s^2 2s^2 2p^6 3s^1

sodium ion.. is going to loose one electron... to gain stability..

so just remove 3s

atomic number of Na is 11
