So in silver atoms there is one electron spin un in 5s shell. How they where deflected in two directions ?

You can have the electron in the spin up or spin down state, which will have opposite dipole values.

What does the spin of the particles says like 1/2, 2/3, 5/2 ?

You can get those spin values from many-electron systems, and you can have a total angular momentum that combines spin and orbital angular momentum where you see 3/2 and 5/2 or more. Electrons by themselves always have spin 1/2, but other particles can have other values for spin. You can have spin 1 and 2 as well.

 

But the values only change by integral amounts, so a system with half-integral angular momentum will never end up with an integral amount.

 

Those are the two possible orientations of the electron spin. You pick an axis for measurement, and the projection along that axis will be either + or - one unit of angular momentum (Planck's constant). We call that up or down.

Spin is a solely quantum-mechanical phenomenon

If this is truly the case, " could " this mean that the h constant has a double? an anti per say?

 

In this model : http://hyperphysics.phy-astr.gsu.edu/hbase/spin.html it shows the formula with h similar as up or down.

I think what confuses many about this is that h = 1 and -1 simultaneously or proportionally sound.

That could mean the h constant is a squared number somehow.

 

 

I assume this is why the wave function focuses on the electron and nothing else.

 

 

In this video however, it shows how the h constant is related to chemical interactions of the periodic table:

But as with the later mentioned if this is such the case, then h must have an anti association.

h is defined to be a positive number; it's a magnitude. If the angular momentum is negative, it's from the spin value, e.g. being -1/2 instead of 1/2

Crazy question then:

 

6.62606957(29)×10⁻³⁴is a positive number????

 

Planck constant

http://en.wikipedia.org/wiki/Planck_constant

 

 

If h is a magnitude I assume its linear, such as a radian?

Otherwise how else could the quantum of action " evolve" in relation to " electron spin orbitals"?

 

h bar?? but that involves another fundamental constant as pi ratio, which is also used to measure:

 

volumes, circumferences, gas prices and etc. Seems pi ratio is virtual involving spin.

 

h is a positive number, Hymm, If this is not the case, then can their ever be something as, traveling back in time??

 

If the h constant is the quanta of action, then I believe so.

But then their is the issues of the suspected " graviton sir"

 

 

Graviton

http://en.wikipedia.org/wiki/Graviton

 

With all its interactions with the quantum world, I assume the electron spin orbitals and shells also connect to the " evolution" of time.

What is the relation between the spin of the particles and magnetic dipole moment ?

Planck constant

Yes. The negative sign in the exponent means that it is a number less than 1.

e.g. 6 x 10^-1 = 0.6

6 x 10^-2 = 0.06

 

There are 33 zeros after the decimal place before you would write the "6". h is a very small number.

Yes. Read the link I provided in my last post for the electron. You can Google for other particles as well; protons and neutrons are more complicated because they are composite particles.

You stated that h is a positive number?

 

" h is defined to be a positive number" --->your words..

 

Why does the exponent matter? I thought this was not the case...

Yes, it's a positive number. The exponent in this notation only tells you how big the number is.

EUREKA! This now makes better sense! tHANKS!

 

So that the exponent works much like translation?

 

HOW ON EARTH DOES SCIENCE MEASURE SOMETHING SOOOOOOO SMALL????

Why, "small"?

 

h is what determines the size of an atom.

 

We observe atoms that constitute a surface by sensing them with the last atom at the tip of a needle, at an atomic force microscope, or a tunnel microscope. The needle is moved mechanically, for instance by a piezoelectric actuator.

Does the spin value changes in excited atoms ?

The overal spin can change, because the spins add. Two spin ½ particles can give you a spin 0 particle or a spin 1 particle. When you excite an atom, the spin can flip. Some excitations only involve a spin flip.

There's actually one thing I've been trying to understand here: Do particles (such as electrons) really spin? As in, do the "surface" of the particle or the quarks inside it actually rotate if you give the particle an anagular velocity, or should particles be imagined as something that no rotation can be attributed to and can only be represented by a position in space (in other words as nothing but points mathematically)?

Do particles (such as electrons) really spin?

The intrinsic spin is not related to the particle spinning about some axes.

 

You need special relativity to understand spin, where it does appear a bit more like a rotation. However, in non-relativistic mechanics spin is just "bolted on to" the theory for phenomenological reasons.

What does the spin like 1/2 1 etc stand for ? of what ?
