Is F2 soluble in water?

does F2 gas dissolve in water? Yes. Fluorine dissolve very well in water and reacts readily with water.

Why are F2 and Cl2 soluble in water?

The halogens are all oxidizing elements with fluorine and chlorine being the most electronegative elements in the group. Hence, the most oxidizing and as a result, both fluorine and chlorine are able to oxidize (react) with water to greater extents forming different products.

F,,²⁺ is paramagnetic. From the molecular orbital electronic configuration, number of electrons present in pi orbitals present is equal to 2.

Is Mo a paramagnetic?

Take a look at the MO diagram and electron configuration for molecular N2 and atomic N. From this picture, it appears that all of electrons in the molecule are paired up and therefore the molecule should be diamagnetic. It turns out that molecular oxygen is paramagnetic.

Is paramagnetic more stable than diamagnetic?

Diamagnetic atoms repel magnetic fields. The unpaired electrons of paramagnetic atoms realign in response to external magnetic fields and are therefore attracted. Paramagnets do not retain magnetization in the absence of a magnetic field, because thermal energy randomizes electron spin orientations.

How do you know if it 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.
