In summary, the spin of a hydrogen atom is determined by its intrinsic angular momentum, which can only take on certain values. Two hydrogen atoms with different spins cannot form a stable H<sub>2</sub> molecule, as their spins must be aligned. However, two hydrogen atoms with the same spin can form a stable H<sub>2</sub> molecule. The spin of a hydrogen atom can be affected by its surroundings through interactions with other atoms or molecules, which can cause it to flip and change its behavior in chemical reactions. The spin of a hydrogen atom is not always the same in all conditions, as it can change in the presence of a strong magnetic field or interactions with other atoms or molecules.

As I know from the laws of chemistry,to form H_2 the H atoms must have opposite spin.
What if they have the same spin?
I mean, can an H atom rotate to swap his spin (i'm not expert of the dynamics of spin), or there is no way to couple them?
In the case I have a gas of H with all of them polarized in the same direction is the formation of H_2 possible?

What spin are you talking about? Electron spin?
 

FAQ: Do two hydrogens with same spin make H_2 ?

How are the spins of hydrogen atoms determined?

The spin of an atom is determined by its intrinsic angular momentum, which is a quantum property. This property can only take on certain values, including half-integer values for hydrogen atoms.

Can two hydrogen atoms with different spins form H2?

No, two hydrogen atoms with different spins cannot form H2. The spins of the two atoms must be aligned in order to form a stable H2 molecule.

What is the significance of two hydrogen atoms having the same spin?

Two hydrogen atoms with the same spin can form a stable H2 molecule. This is because their spins are aligned, making it energetically favorable for them to bond together.

How is the spin of a hydrogen atom affected by its surroundings?

The spin of a hydrogen atom can be affected by its surroundings through interactions with other atoms or molecules. These interactions can cause the atom's spin to flip, changing its behavior in chemical reactions.

Is the spin of hydrogen atoms always the same in all conditions?

No, the spin of hydrogen atoms can change in different conditions. For example, in the presence of a strong magnetic field, the spin of a hydrogen atom can align with or against the field, depending on its energy state. Additionally, interactions with other atoms or molecules can also affect the spin of hydrogen atoms.
