A1.5g sample of a compound, consisting of elements chlorine and chromium, was dissolved completely in water. the solution was added to excess silver nitrate solution, agno3. all the chlorine from the samplebwas converted to 4.074g of silver chloride precipitate, agcl. determine the number of moles of ag+ and cl- in the silver chloride precipitate.

sry but any answer choices

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.
