the answer is false because not all countries have geysers under their crust. for example, iceland uses geothermal energy because it is available every in their country.  

it's c. elements are placed in rows based on how may valencies electrons have.

let that person have a turn to speak : )

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.
