Standard State of Elements

Postby Srbui Azarapetian 2C » Sun Jan 21, 2018 3:35 pm

What are all the elements for which need to know the standard states of and that their enthalpy of formation of its most stable form is zero? (ex. O2, N2)

I would know that at standard states carbon is a solid, N2, O2, F2, Cl2 are gasesm and Br2 is a liquid and I2 is a solid. I helps to know these things especially for standard enthalpies of formation when you are not given an equation or anything.
