Why do some atoms not follow the Aufbau rule? 1: Some elements are just more naturally full of more energy placing electrons in higher energy sublevels 2: To make chemistry harder than it already is 3: Filled and half filled orbitals are stable 4: There is no instance where everyone follows the rules as they should

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

Identify the lewis acid in this balanced equation: ag+ + 2nh3 -> ag(nh3)2+a. ag+b. nh3c. ag(nh3)2+

Covalent bonds generally form when the bonded elements have a difference in electronegativity less than 1.5. subtract the electronegativities for the following pairs of elements and predict whether they form a covalent bond. electronegativity difference of c and c: ionic covalent electronegativity difference of mg and cl: ionic covalent
