Question

Give the electron configuration for Na using the short hand, noble gas method

Answer 1

Na:[He]3s¹

Step-by-step explanation:

[He] => core structure => Helium ([He]1s²)

3 => principle energy level of valence electrons

s => orbital geometry of valence structure => spherical

s¹ => orbital orientation of valence structure => 1 orientation for sphere

superscript 1 => 1 unpaired electron in orbital
