Question

write the sub shell electronic configuration of the following atom na-11​

Answer 1

Answer:

When we write the configuration we'll put all 11 electrons in orbitals around the nucleus of the Sodium atom. We'll put six in the 2p orbital and then put the remaining electron in the 3s. Therefore the sodium electron configuration will be 1s22s22p63s1

Answer 2

Answer:

2-8-1 is the electronic configuration of sodium
