A solution consists of 51.2 g of silver nitrate (AgNO3), 113.8 g water, and has a volume of 124 mL. Calculate the weight percent of AgNO3, the molality of AgNO3, the mole fraction of AgNO3, and the molarity of AgNO3 in the solution.

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.
