Question

Write the electron configuration, orbital filling diagram, and shorthand notation for Gallium

Answer 1

Electron configuration-

`1 s^(2)  2 s^(2)  2 p^(6)  3 s^(2)  3 p^(6)  4s^(2)  3d^(10)  4p^(1)`

Shorthand notation-
[Ar]
`4s^(2)  3 d^(10)  4p^(1)`

And I can't really show it the orbital filling diagram, but it would look exactly like your last problem except the 4p orbital would have one "half" arrow on the first line pointing upwards

Hope this helps!

Answer 2

farmula of electronic configuration is 2(n) n=atomic number . then put into shells.
