Lewis dot structure
100

Consists of elements symbol which represents the atomic nucleus and inner-level electrons, surrounded by dots representing atoms valence electrons.

What is the electron dot structure?

200

This element only needs two electrons in its Lewis dot structure, this makes it an exception to the octet rule.



Hydrogen

300

This family has a complete octet.

Family 18

400

This is the total number of valence electrons in the Lewis structure for NH₃.
