1.) Rank the alkaline earth cations (Mg^2+, Ca^2+, Sr^2+, Ba^2+) from the one forming the most precipitates to the one forming the least precipitates. a.) How does the solubility of alkaline earth cations (i.e., tendency to precipitate or not) change with position in the periodic table? (choose one of the options to make both of the following sentences correct) The cation higher in the table has LOWER / HIGHER solubility. The cation lower in the table has LOWER / HIGHER...

1. Why is the Electron Affinity of chlorine more favorable (that is, more negative) than fluorine? This is surprising as fluorine is the most electronegative element. 2. The second Electron Affinity for oxygen is positive and very large, meaning it is unfavorable. But the most common ion of oxygen is oxide, O2−. How can you explain this, aside from using the octet rule? 3. Ammonia (NH3) has a greater dipole moment than nitrogen trifluoride (NF3). This means that ammonia is...

Periodic Trends in Group
II
Objective
In this experiment, the trend in one of the several periodic
properties for group II of the Periodic Table will be
determined.
Introduction
Elements in the same group of the Periodic Table have similar
chemical and physical properties that gradually change as one goes
from one element in the group to the next. By observing the trends
in properties, the elements can be arranged in the order in which
they appear in the Periodic...
