2) Explain how two students could perform chromatography on the same mixture, the colored samples all move different distances, yet they can correctly identify the component parts.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

b.false that your answer

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.
