    Atom Charge
AI Thread Summary
The charge of a stable atom, such as the chromium isotope 52Cr, is determined by the balance of protons and electrons. Since every atom has an equal number of protons and electrons, the net charge of a neutral atom is zero. This principle applies universally to all neutral atoms. The initial confusion about calculating the charge stemmed from focusing on the charge of the nucleus rather than the overall atom. Therefore, the conclusion is that the atom is neutral.

Homework Statement


i have a question that i really need help on!

A stable isotope of chromium is
52
Cr
24

Calculate the Charge of the atom!

Homework Equations


The Attempt at a Solution


what i thought is 24x(1.60x10-19)
but this gives me the charge of the nucleus!

please help!

does that mean its neutral? and does this apply for ALL atoms?!
 
Yes.
 
oh :rolleyes:!
thanks for you help!
 
Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Thread 'A cylinder connected to a hanged 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...
