Problem: Treating bismuth with fluorine gas forms BiF5. Use the electron configuration of Bi to explain the formation of a compound with this formulation.

FREE Expert Solution

Valence electrons (outermost electrons) are the electrons involved in bond formation. 

Now, let’s write the condensed electron configuration of Bi and determine its outermost electrons.

Recall that in a neutral atom:

            Atomic number = # of protons = # of electrons

Bi (refer to the periodic table):

Atomic Number = # of e- = 83 e-

Nearest noble gas: Xe
