Notes
... If iron is to rust the metal must come into contact with both oxygen and water. We can slow down the process and prevent rusting by using different methods of protection. The metal can be given physical protection to hinder corrosion. Physical protection means that air and water are prevented from r ...

... • These are positively charged ions, resulting from a loss of an electron. • Metals tends to lose electrons from their highest occupied energy levels to become cations. This leaves a complete octet in the next-lowest energy level. • The charge for a cation is written as a number followed by a plus s ...

... The difference in arrival times at the electron detectors for correlated pairs will always be the same, whereas random pairs have random arrival times. Collecting data for a large number of collisions over a range of energy and momentum values directly maps the probability density of the target elec ...

... If the difference in electronegativity is large enough the bond between the atoms will have polarity. What is this called? Any diatomic molecule will have a dipole moment. When will they not? Some polyatomic molecules can have dipole moments. When will this occur? IV. Stable Electron Configurations ...
