To solve this problem we will apply the concept related to the magnetic dipole moment that is defined as the product between the current and the object area. In our case we have the radius so we will get the area, which would be
Once the area is obtained, it is possible to calculate the magnetic dipole moment considering the previously given definition:
Therefore the magnetic dipole moment is
Answer:
Explanation:
We are given that
Atomic number=2
We have to find the total negative charge on the electrons in one mole of Helium.
We know that atomic number=Proton number
Proton number=Number of electrons=2
Number of electrons in Helium=2
1 mole of Helium= atoms
We know that q=ne
Where n =Number of fundamental units
e=Charge on electron
1 e=
Using the formula
Total negative charge in 1 mole=
Hence, the total negative charge on the electrons in 1 mole of Helium=
