Label the following as (I) increasing, or (D) decreasing the solubility of the carbon dioxide in a soft drink: Leaving the lid on the container (i. e. keeping the pressure high)

Removing the lid from the container

Keeping the container in the refrigerator

Warming up the liquid in the container

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.
