Atomic Spectra Lab Purpose: The purpose of this lab was to identify the wave length and spectra of the two elements‚ mercury and hydrogen. The wavelengths of the two elements represent the characteristic energies of moving electrons. The spectra of the two elements are what side of the energy spectrum their wavelengths are on. Materials: • Hydrogen lamp • Mercury lamp • 2 diffraction devices • Flashlight • Paper • Pencil • Calculator Procedure: 1. Place

Atomic War or Peace? Was the dropping of the atomic bomb on Japan justified? Many people believe that it was very justified‚ but was it? Some reasons could have been the attack on Pearl Harbor‚ the destruction of Japans power to make war‚ also what seemed to the only answer to end war. “I wouldn’t hesitate if I had the choice. I’d wipe ‘em out. You’re gonna kill millions of innocent people‚ but at the same time we’ve never fought a war anywhere in the world where they haven’t fought and killed

Atomic Structure & Electricity 1. Draw an atom with an atomic number of 12. Label the protons‚ neutrons‚ and electrons. Use the periodic table to identify which atom you have drawn. 2. How many valence electrons are present in this atom? 2 3. Would this atom prefer to gain or lose electrons? Why? Lose‚ because the octet rule dictates that if there is less than 4 valance electrons‚ they would prefer to leave the atom. 4. Describe the differences between conductors‚ semiconductors

Sir J.J.THOMSOM is to physics what electron is to an atom. He charged the world of physics with his discoveries and gave momentum to atomic physics. Physics is what today because of this British scientist who is regarded as the greatest experimental physicists of this century. A bookseller’s son‚ Thomsom studied at the Owens College and later at the Manchester University. He wanted to become an engineer‚ but his father’s death in 1872 forced him to study Mathematics‚ Physics and Chemistry as he

Integrated Physics and Chemistry – Unit 2: The Structure of Matter Experiment: Atomic Structure In this experiment‚ you will have a chance to test the hypothesis that Ernest Rutherford used when determining the size of the nucleus. In his "gold foil experiment‚" Rutherford shot alpha particles at gold atoms. Once he realized that the alpha particles were hitting a concentrated positive mass‚ he developed the nuclear model of the atom. Next‚ he set out to determine the relative size of the nucleus

They are not afraid to dream‚ and to yearn for everything they would like to see happen to them in their lives. But‚ as time passes‚ a mysterious force begins to convince them that it will be impossible for them to realize their Personal Legend."(Pg. 21) This quote is when the king meets up with Santiago

this passage from Star Wars to a scene from The Alchemist. These dialogues are very alike in both characters‚ and conversation topics. Luke is very much like Santiago‚ and the Alchemist like Obi-Wan. Both duets discuss a partnership in which they travel to a place far away to achieve their personal legend‚ or life goal. Obi-Wan says‚ “...come away with me‚ and go to Alderaan” [II‚ II‚ Line 120] to Luke in Star Wars‚ and in The Alchemist‚ the Alchemist similarly states “I am going to guide you across
