Question 5

Which of the following statements is/are CORRECT?
1)A paramagnetic substance is attracted to a magnetic field.
2)An atom with no unpaired electrons is ferromagnetic.
3)Atoms with one or more unpaired electrons are paramagnetic.
A) 1 only
B) 2 only
C) 3 only
D) 1 and 3
E) 1,2,and 3

Accepted Answer

Statement 1 is correct as paramagnetic materials are attracted to magnetic fields due to the presence of unpaired electrons which align with the external magnetic field.
Statement 2 is incorrect, as an atom with no unpaired electrons cannot be ferromagnetic. Ferromagnetic substances require unpaired electrons with parallel spins to generate a magnetic moment.
Statement 3 is correct as atoms with one or more unpaired electrons exhibit magnetic properties and are paramagnetic.

Question 8

What is the value of the spin quantum number for an electron in a 4p orbital?
A) 4
B) 1
C) either  
Or  
D)
  
E)

Accepted Answer

The spin quantum number for an electron is always either +1/2 or -1/2. The orbital quantum number for a 4p orbital is 1, which means there are three possible values for the magnetic quantum number: -1, 0, and +1. Therefore, there are two possible spins for each magnetic quantum number, giving a total of six electrons in the 4p orbital. The correct notation for the electron in question would be 4p¹. Since there is only one electron in this orbital, it can have a spin of either +1/2 or -1/2, giving two possible options for the spin quantum number. Therefore, the answer is C: either +1/2 or -1/2.

Question 13

Which of the following statements is/are CORRECT?
1)A diamagnetic substance is strongly attracted to a magnetic field.
2)Substances that retain their magnetism after they are withdrawn from a magnetic field are called ferromagnetic.
3)Most transition metals and all lanthanide metals are ferromagnetic.
A) 1 only
B) 2 only
C) 3 only
D) 1 and 3
E) 1,2,and 3

Accepted Answer

1) A diamagnetic substance is actually weakly repelled by a magnetic field.
2) Substances that retain their magnetism after they are withdrawn from a magnetic field are called permanent magnets. 
3) Most transition metals and all lanthanide metals are actually paramagnetic or diamagnetic, not ferromagnetic.
