Write the electron configuration for sodium.

1s^2..2s^2..2p^6..3s^1

Explanation:

Since sodium has 11 electrons...its electron configuration is...;

1s^2..2s^2..2p^6..3s^1

;The powers of the energy levels(i.e s,p,d) should all add up to the number of electrons in an atom

*.When writing...please do not separate them.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
