Question

How many p-orbitals are occupied in an N atom?

Answer 1

As per the Aufbau principle, p orbitals are filled once the s orbitals are commonly filled. Quantum mechanics states that for every energy level, there are three orbitals in a p subshell. The orbitals namely ${p_x}$ , ${p_y}$, and ${p_z}$ and these orbitals are arranged in alignment with the x, y, and z axis.

Complete step by step answer:
We must know that the Hund’s rule states that before pairing of electrons the orbitals in a given subshells are by one electron. Thus the orbitals ${p_x}$ and the ${p_y}$ and ${p_z}$ will occupied by one electron before a second electron occupies the ${p_x}$ orbital.
Nitrogen has 3 p orbitals which are occupied by a single electron.
We know that the electron configuration for nitrogen is $1{s^2}2{s^2}2{p^3}$
From the electronic configuration it is known that the total number electrons are 7 and it is the atomic number of nitrogen. Neutral atoms have the identical atomic number as electrons.

Note: We know that among the elements of the period 15 nitrogen is the lightest element.
The number of valence electrons in nitrogen is five.
Aside from its utilization in manures and energy-stores, nitrogen is a constituent of natural mixes as different as Kevlar utilized in high-strength texture and cyanoacrylate utilized in superglue.
As we know that nitrogen is a constituent of each major pharmacological medication class, including anti-infection agents.
Numerous medications are impersonates or prodrugs of common nitrogen-containing signal particles: for instance, the natural nitrates dynamite and nitroprusside control pulse by using nitric oxide.
Numerous eminent nitrogen-containing drugs, for example, the regular caffeine and morphine or the engineered amphetamines, follow up on receptors of creature synapses.
