From what I've learned atoms with unpaired electrons are paramagnetic and those without are diamagnetic. Strontium has electron configuration of [Kr] 5s^2 so why is it paramagnetic?
Magnetism is a phenomenon where certain materials, such as iron and nickel, have the ability to attract or repel other materials. This is due to the alignment of electron spin within the material, which creates a magnetic field.
Electron spin is an intrinsic property of electrons, meaning it is a fundamental aspect of their nature. It refers to the directional rotation of an electron around its axis, which can be either clockwise or counterclockwise.
Electron spin is responsible for creating the magnetic moments within materials. When the spins of electrons are aligned, they create a magnetic field that can attract or repel other magnetic materials.
Paramagnetism occurs when the spins of electrons are randomly oriented, but can be temporarily aligned in the presence of a magnetic field. Diamagnetism occurs when the spins of electrons are paired and cancel each other out, making the material repel magnetic fields. Ferromagnetism occurs when the spins of electrons are permanently aligned, creating a strong and stable magnetic field.
Magnetism and electron spin have many practical applications, including in compasses, electric motors, MRI machines, and data storage devices such as hard drives and credit cards. They are also used in research for studying materials and particles at the atomic level.
