Calculate the atomic mass of sulfur if the four common isotopes of sulfur have masses of 31.972 amu (95.00 % abundance), 32.971 amu (0.76 %), 33.967 amu (4.22 %), and 35.967 amu (0.014 %).

32.063 u

Explanation:

The average atomic mass of a chemical element is calculated by taking into account the atomic masses of its naturally occurring isotopes and their respective abundances.

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.
