In Germany between 1933 and 1945, every aspect of life was influenced or affected in some way by Adolf Hitler and his Nazi Party. In some cases, this worked for the betterment of the average German – ordering economic effort, stimulating industry, creating employment, improving standards of living, and re-igniting a sense of pride in the nation. In other cases totalitarian control directed the nation down paths which had an opposite effect. Through the use of rare historical footage from archives around the world, this video succinctly portrays the essential nature of life under Adolf Hitler, in all its major guises.

Holding Electrons
The attraction of each electron in an atom is unique. This is due to the charge on the nucleus, the distance and repulsion by other electrons.
IONIZATION ENERGY. The work required to remove an electron for an atom. No two electrons in an atom have the same value. This increases at certain stages leading to the energy shell model of the atom. ELECTRO NEGATIVITY. This is the number describing a particle’s ability to retain an electron in a chemical reaction. It describes and predicts the degree of polarity of a chemical bond. ACTIVITY SERIES. The ability of atoms to hold onto their electrons is also expressed in the activity series of the elements. The concepts of electron transfer and voltage production in cells are explored at their simplest levels. -
