Answer:
Explanation:
Sodium Na has 11 electrons.
Sodium has an electronic configuration of 2, 8, 1.
The valence electron is the number of electrons in the last shell.
The number of valence electrons in sodium is 1.
Answer:
Number of valence electrons in sodium is 1 as we know the electronic configuration of sodium that is
[tex]1s^2,2s^2,2p^6,3s^1[/tex]
as there is only one electron in third sub-shell so the Number of valence electrons in sodium is 1
