- Imagine that you are holding a lead weight on the palm of
your hand. If the weight of
the lead is 0.80 N and the
bottom of the weight has an
area of 0.016 m2, what is the
pressure on the palm of your
hand?

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.
