Chlorine's Electron Configuration and Magnetism

The video tutorial explores whether the chlorine atom is paramagnetic or diamagnetic, focusing on its electron configuration. It explains that unpaired electrons make an atom paramagnetic, while paired electrons result in diamagnetism. The electron configuration of chlorine is detailed, showing one unpaired electron, making it paramagnetic. The video also discusses chlorine in compounds, like Cl2, which is diamagnetic due to paired electrons.

What determines if an atom is paramagnetic?

• Presence of paired electrons

• Presence of unpaired electrons

• Number of protons

• Number of neutrons

What is the electron configuration of chlorine up to 2p?

• 1s2 2s2 2p5

• 1s2 2s2 2p6

• 1s2 2s2 2p4

• 1s2 2s2 2p3

How many unpaired electrons does a chlorine atom have?

• None

• One

• Two

• Three

What type of magnetic property does a chlorine atom exhibit due to its unpaired electron?

• Diamagnetic

• Ferromagnetic

• Paramagnetic

• Antiferromagnetic

In what form is chlorine most commonly found in nature?

• As Cl2

• Bonded with sodium

• As a single atom

• As a free radical

What is the magnetic property of Cl2?

• Paramagnetic

• Ferromagnetic

• Antiferromagnetic

• Diamagnetic

Why is Cl2 considered diamagnetic?

• It is a noble gas

• It has paired electrons

• It has unpaired electrons

• It has a high atomic number

What is the significance of paired electrons in determining magnetic properties?

• They increase the atomic mass

• They cause attraction to magnetic fields

• They cause repulsion from magnetic fields

• They have no effect on magnetic properties

What is the main reason a chlorine atom is paramagnetic?

• It is a noble gas

• It has an unpaired electron

• It forms ionic bonds

• It has a high atomic number

What is the overall magnetic property of molecular chlorine (Cl2)?

• Paramagnetic due to unpaired electrons

• Antiferromagnetic due to opposing spins

• Ferromagnetic due to strong magnetic domains

• Diamagnetic due to paired electrons
