True or false? Most salts found in the ocean originated on land

false \

explaintion

then wound pond and lakes be salt water

The salt in the ocean mainly comes from runoff from the land and openings in the seafloor. So, I would say false.

the answer is c

tell me if wrong

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.
