Question

What is the electron structure of a sodium atom?

A. 1s22s22p63s1
B. 2s22s22p63s1
C. 1s22s22p63s6
D. 1s12s22p63s1

Answer 1

1s22s22p63s1 is the electronic configuration of sodium.

Step-by-step explanation:

Answer 2

There are 11 electrons in Sodium ( find this on the periodic table).

Then you need to arrange the electrons in the orbitals around the nucleus.

The structure would be written as A. 1s^22s^22p^63s^1
