What is a limitation of using a chemical formula, such as CeH1208, to represent a compound?
O The chemical formula does not show the types of elements that make up the compound.
O The chemical formula does not show how the atoms are connected to one another.
O The chemical formula does not show the number of atoms of each element in a molecule.
O The chemical formula does not show the chemical symbols of the elements in the compound.

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.
