The Group 2A(2) elements are called alkaline earth metals because their oxides give (alkaline) solutions and melt at such temperatures that they remained as solids ("earths") in the alchemists fires. denser low for 2A metals than larger lower The melting and boiling points are much for the corresponding 1A metals. ences smaller oxidizing Compared to corresponding Group 1A(1) elements, Group 2A(2) elements have metallic bonding and atomic sizes which makes them harder and...

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...
