The above resources can be classified as renewable or non-renewable. Some resources are constantly produced on the earth and are known as renewable resources. Others are not replenished and are called non-renewable sources. Resources Renewable resources Non-renewable resources Solar power Wood Hydr..

In metals, the conduction band and valence band partly overlap each other and there is no forbidden energy gap. In insulators, the conduction band is empty and valence band is completely filled and forbidden gap is quite large = 6 eV. No electron from valence band can cross over to c..

As the alkali metals have very low ionization energies, the energy from the flame of a bunsen burner is sufficient to excite the electrons of alkali metals to higher energy levels. The excited state being unstable, these electrons return to their original energyh..

All alkali metals are soft and have low melting and boiling points. As alkali metals have only one valence electron per metal atom, the energy binding the atoms in the crystal lattice of the metal is low. Consequently, the metallic bonds in these metals are not very strong and their melt..

Introduction - For thousands of years people have looked up at the stars and wondered what lay beyond them. It was once believed that the earth was the center of the universe and that everything moved around it. It was later discovered that the earth moves around the sun. Today, powerful ..
