N the nucleus, there are protons and neutrons. That's two parts.
<span>Outside the nucleus, there are electrons. That's a total of three parts and that is all that chemists discuss. Theoretical physicists talk about other sub nuclear "parts", but if you include them, the number goes way over 5. </span>
<span>The "shells", "sub-shells", "orbits", "orbitals", "probabilities" and the like are not physical parts, but only descriptions of energy</span>
Answer:
the electron cloud model is the current model of atom
nebula is an interstellar cloud of dust, hydrogen, helium and other ionized gases. although denser than the space surrounding them, most nebulae are far less dense than any vacuum created on earth – a nebular cloud the size of the earth would have a total mass of only a few kilograms. (wikipedia)

The equilibrium constant (K) : 11.85
<h3>Further explanation</h3>
Given
Reaction
N₂(g) + 3H₂(g) ⇒ 2NH₃(g)
Required
K(equilibrium constant)
Solution
The equilibrium constant (K) is the value of the concentration product in the equilibrium
The equilibrium constant based on concentration (K) in a reaction
pA + qB -----> mC + nD
![\tt K=\dfrac{[C]^m[D]^n}{[A]^p[B]^q}](https://tex.z-dn.net/?f=%5Ctt%20K%3D%5Cdfrac%7B%5BC%5D%5Em%5BD%5D%5En%7D%7B%5BA%5D%5Ep%5BB%5D%5Eq%7D)
For the reaction above :
![\tt K=\dfrac{[NH_3]^2}{[N_2][H_2]^3}\\\\K=\dfrac{0.1^2}{0.25\times 0.15^3}\\\\K=11.85](https://tex.z-dn.net/?f=%5Ctt%20K%3D%5Cdfrac%7B%5BNH_3%5D%5E2%7D%7B%5BN_2%5D%5BH_2%5D%5E3%7D%5C%5C%5C%5CK%3D%5Cdfrac%7B0.1%5E2%7D%7B0.25%5Ctimes%200.15%5E3%7D%5C%5C%5C%5CK%3D11.85)
Answer:
to fall towards 7, making the solution less alkaline as more water is added.
