Which of the following values is measured the LEAST precisely? * 22mL 45.2mL 50mL 100mLchem

If you're looking at the data as a whole, it would most likely be 100ml.

Explanation: The definition of precise is data close together so 100ml is furthest away from the other recorded numbers

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.
