Question

(11) Write the electronic configuration of the elements Na , AI, S2-​

Answer 1

Answer:

Ne] 3s² 3p¹

Aluminium/Electron configuration

)The electronic configuration of Na

is 1s2

2s2

2p 6

The S2- ion, the simplest sulfur anion and also known as sulfide, has an electron configuration of 1s2 2s2 2p6 3s2 3p6. A neutral atom of sulfur has 16 electrons, but the atom then gains an additional two electrons when it forms an ion, taking the total number of electrons to 18.

Answer 2

Answer:

electronic configuration of Na is : 2,8,1

electronic configuration of Al is : 2,8,3
