(2) negative ion with a radius larger than the radius of the atom
(3) positive ion with a radius smaller than the radius of the atom
(4) positive ion with a radius larger than the radius of the atom

Why are the trends and exceptions to the trends in ionization energy observed?

Pegmatites are igneous rocks in which the individual minerals are very large. typically, the minerals are all light-colored quartz, feldspar and muscovite. if you were given a black and white photograph of a pegmatite in a quarry (where the rock has been blasted and broken), what physical properties could you use to identify those three minerals in this hypothetical photo? describe each mineral and the specific diagnostic properties. be specific.
