Finasteride treats male pattern hair loss by blocking the body's production of a male hormone in the scalp that stops hair growth.

Valence Electrons and Energy Levels. The electron is one of the most important factors in determining how an atom will react with another atom or molecule. A single electron can make all the difference in the properties of an atom. For example, sodium has one outer electron, located in that 3 s orbital.nergy of Valence Electrons. Aside from the number of valence electrons an atom has, the energy they have (or the energy level that they are in) is the last bit of information that helps predict how an atom will react. Let's take one look at the first column of elements.
