A 1935 paper by Bertha Swirles that was largely ignored for decades showed the impact of this theory on atomic structure. Ahuja et al. found in 2011 that this theory is responsible for about 80 percent of the voltage in lead-acid batteries. (15[1])The only stable monatomic metal anion, which forms a compound with cesium, is stable due to this theory. This theory causes states with two unshared valence electrons to be stable in the inert pair effect. Corrections due to (*) spin-orbit coupling and this theory are used to approximate the fine structure of a hydrogen-like atom. (-5[1])Poor electron shielding and a phenomena predicted by this theory impact the 6s orbital of lanthanides. (10[1])This theory explains why mercury is a liquid at room temperature and gold appears yellow. (10[1]-5[1])For 10 points, the 1s orbital shrinks more in heavier atoms due to what theory of Albert Einstein? ■END■ (10[2])
