What happens if you make all different chemicals together including gases

Though this may seem like a sure-fire way to eliminate household germs and diseases, the mixing of chemicals can produce highly toxic fumes or create an extremely corrosive product. The Skokie Fire Department strongly encourages citizens to refrain from the mixing of household chemicals.

Explanation:

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.
