AI Thread Summary
The discussion centers on the force versus energy curve of magnesium oxide (MgO) ionization at a distance of 0.22 nm. Participants express uncertainty about how to sketch this curve, with one mentioning the Rydberg equation, which is typically applied to atomic rather than ionic systems. There is a request for clarification on molecular ionization concepts to better understand the topic. The conversation highlights a gap in knowledge regarding the specific application of the Rydberg equation to ions. Overall, the thread seeks guidance on the fundamental principles of molecular ionization and its graphical representation.

The distance between two ionizations of MgO is .22 nm. Sketch its curve of Force vs. energy.

Its a question,one of my classmates requested me to find the solution and its not related to the things I'm studying at university.
The only thing I remember about it is the ridberg equation which as I remember is for atoms not ions.

thanks

Could you give me some information about molecular ionization?
thanks
 
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...
