How do periodic trends affect acidity strength?
How do periodic trends affect acidity strength? In each vertical row of the periodic table, acidity usually increases with increasing atomic number because the valence (bonding) electrons are farther and farther away from the nucleus and less strongly attracted to the positive nucleus. Why does acid strength increase across a period? Going across a period the acid strength increases as there is an increase in electronegativity and the molecule gets more polar, with the hydrogen getting a larger partial positive charge. This makes it easier to heterlytically cleave the E-H bond to produce a stable anion. What is the trend...
