Nitrogen: Atomic Number 7 & Electron Configuration

  • #1
Homework Statement
I need help with this
Relevant Equations
N/A
Nitrogen has an atomic number of 7. Thus, A nitrogen atom has 7 electrons. Nitrogen’s electron configuration is: [He] 2s2 2p3
The nitrogen element has five valence electrons present in 2s and 2p orbitals. So it would have five dots placed around the symbol for nitrogen.

Is this correct? I need two major problems.

That’s not correct for an atom of nitrogen. Only show the 5 valence electrons. Look at how they are grouped.

Yes, that’s what I’ve stated. Can you help me explain how they grouped incorrectly?

Dot diagrams represent the sub-orbitals in the valence shell. There are four sub-orbitals around nitrogen. How do you fill each of these sub-orbitals? How is it shown above?

It has 3 p electrons so put a single dot on each three of the remaining sides
