are only in their excited for a brief moment. When the electron moves back down to a lower energy state‚ it emits light and produce a flame color.1 Sometimes there is more than one flame color because an electron might go from the 4s orbital then go to the 2p orbital which means two colors will be produced. Every element emits a different flame color or colors. These colors can be put on a bright line spectra which shows every color that the element produces in a

It was a dark and thunderous night when returning home from my girlfriend’s house in Westville. Most of the way had clearly lit streets‚ until I got to the junction of Buttercup Lane and Meadow Street. I had a choice of taking a short cut through my local park‚ or walking around it‚ which would add a further mile to my journey. It was getting late‚ so I decided to take the short cut. The park was always dark with little or no illumination‚ except for the light given from the moon and the stars.

pycnocline 4. What is the difference between longitudinal waves and transverse waves? (Ch. 8‚ Section “How do waves move?” 5. Describe circular orbital motion. d. The water itself doesn’t travel the whole distance‚ but the waveform does. As the wave travels‚ the water passes the energy along by moving in a circle called circular orbital motion. 6. How can you calculate wave speed? e. Wave Speed (S) = Wavelength (L) / Period (T) 7. What are shallow-water waves?

Chemical Bonding Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms. The bound state implies a net attractive force between the atoms ... a chemical bond. The two extreme cases of chemical bonds are: Covalent bond: bond in which one or more pairs of electrons are shared by two atoms. Ionic bond: bond in which one or more electrons from one atom are removed and attached to

Johannes Kepler was born December 27‚ 1571. He was a German mathematician‚ astronomer‚ astrologer‚ and a key figure in the seventeenth century. He is best known for his eponymous laws of planetary motion. He believed that God had created the world according to an intelligible plan that through the natural light of reason. Kepler’s first major astronomical work‚ Mysterium Cosmographicum‚ was the first published defense of the Copernican system. On July nineteenth 1595 he had an epiphany. He realized

comprised of protons and neutrons while only 1 ounce of their being would be made of electrons. Both the protons and neutrons reside within the nucleus. Protons have a positive charge‚ neutrons have no charge; they are neutral. Electrons reside in orbitals around the nucleus and have a negative charge. Atomic number is derived from the number of protons in an atom. Example‚ Helium‚ (H) = 1. The number of protons in an element is constant (e.g.‚ H=1‚ Ur=92) but neutron number may vary‚ so mass number

What do racism‚ poverty‚ and violence have in common? They all result from one major problem: lack of education. Lack of education is a problem that has plagued many nations for years. Once in this crisis‚ it takes a long time to recover and rebuild a nation that can rise above the problems that illiteracy causes. This social issue is very prevalent in reality and many books focus on this point. The Kite Runner‚ by Khaled Hosseini‚ accurately depicts the problems of poverty and ignorance caused by

rarely as the metal. Why these elements are rarely found as the metal? (Refer to the relative measurements tabulated in the form of electronegativities‚ ionization energies‚ or reduction potentials). These are due to the fact that their outer most orbital (ns1 valence electron configuration) has tendency to lose electron very easily and make stable configuration. The single valence electron is relatively far from the nucleus‚ only weak attractions exist in the solid between delocalized electrons and
