Nitrogen gas, N2, is the only gas generated from the decomposition of an unknown substance. The reaction is run to completion and the gas produced was collected over water at a temperature of 298 K. The total pressure of the gas collected over the water is measured to be 2.25 atm. If the partial pressure of water at this temperature is 0.0351 atm then determine the partial pressure of N2 gas produced. A. 1.80 atm
B. 2.21 atm
C. 2.28 atm
D. 3.10 atm

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.
