Consider this molecular-level representation of a mixture of gases. There are three gas particles containing two spheres. There are six gas particles containing a single sphere of a different color. There are five gas particles containing a single sphere of a third color. If the partial pressure of the diatomic gas is 0.780 bar , what is the total pressure of the system

it would be a gas formation

the answer is 75.0%.

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
