magnetic property of o2 molecule


​

Answer 1

$\huge\colorbox{red}{Explanation:-}$

Molecular oxygen ( O2 is paramagnetic and is attracted to is paramagnetic and is attracted to the magnet. In contrast, molecular nitrogen, N2 , has no unpaired electrons and is diamagnetic; it is therefore unaffected by the magnet. Diamagnetic substances are characterized by paired electrons, e.g., no unpaired electrons. According to the Pauli Exclusion Principle which states that no two electrons may occupy the same quantum state at the same time, the electron spins are oriented in opposite directions. This causes the magnetic fields of the electrons to cancel out; thus there is no net magnetic moment, and the atom cannot be attracted into a magnetic field. In fact, diamagnetic substances are weakly repelled by a magnetic fieldas demonstrated with the pyrolytic carbon sheet ....

How to know if a Substance is Paramagnetic or Diamagnetic??????

➡ The magnetic properties of a substance can be determined by examining its electron configuration: If it has unpaired electrons, then the substance is paramagnetic and if all electrons are paired, the substance is then diamagnetic. This process can be broken into three steps:

• Write down the electron configuration
• Draw the valence orbitals
• Identify if unpaired electrons exist
• Determine whether the substance is paramagnetic or diamagnetic

Answer 2

Answer:

As shown in the video, molecular oxygen (O2 is paramagnetic and is attracted to is paramagnetic and is attracted to the magnet. In contrast, molecular nitrogen, N2, has no unpaired electrons and is diamagnetic; it is therefore unaffected by the magnet.
