AI Thread Summary
To determine carbon's ground state electron configuration, the relevant principles include the Aufbau Principle, which dictates the order of orbital filling, and Hund's Rule, which addresses the distribution of electrons among orbitals. The Pauli Exclusion Principle is also significant, as it ensures that no two electrons can share the same set of quantum numbers, preventing them from collapsing into the lowest energy state. The discussion leans towards the conclusion that all three principles are essential for accurately describing electron configurations. The initial uncertainty about whether to include the Pauli Exclusion Principle highlights its critical role in the overall understanding of electron arrangements. Ultimately, recognizing the interplay of these principles is vital for grasping the concept of electron configurations in atoms.

Which principle or rule must be used to determine the correct electronic configuration for carbon in its ground state?
a.Aufbau Principle
b. Hund's Rule
c. Pauli Exclusion Principle
d. (A) and (B) only
e. All three

I know for a fact that Aufbau's and Hunds rule deal with ground state configuration i just don't know if you consider Paulis rule, which says that no two electrons can have the same 4 quantum numbers, when you are conforming an electron to its ground state?

Can any help me, my answer as of know is D but I am second guessing myself with E?

The Pauli Exclusion Principle is the reason why all of the electrons in any atom don't just collapse to the first orbital. If they did, they'd all have identical quantum numbers.

Does that help?
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
