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

casted an aura of heavenly peace over its three hundred and fifty thousand inhabitants. That peaceful heaven‚ however‚ was about to be obliterated by a destructive new weapon created by the United States of America. That morning‚ the first nuclear bomb ever created was deployed over Hiroshima. Its virtually unimaginable power obliterated the entire city along with forty percent of its population within seconds. America succeeded in creating the most destructive weapon mankind had ever seen‚ and it

Population Bomb The continuous increase of population in the world has become a major problem to planet earth. Oftentimes‚ it is referred to as the population bomb owing to the adverse impacts it creates on the world today. Such population explosion leads to social‚ economic and environmental problems. This prompted the enactment of global protocols‚ regional agreements and localized legislations which are all geared up towards resolving mounting social‚ economic and environmental problems.

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

Environmental pollution In this topic we are going to deal about different types of pollution and due to these types of pollution how our environment is facing disasters and calamities. Introduction: Environmental pollution can be defined as “the unfavorable alteration of our surroundings” Types of pollutants: 1. Bio degradable pollutants - decompose rapidly by natural processes. 2. Non-degradable pollutants-do not decompose or slowly decompose in the environment. Pollutions are different

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

bombing and blockade until Japan surrenders. 2. Invade Japan. 3. Redefine “unconditional surrender” in such a way to induce Japanese Government to surrender. 4. Frighten Japan into surrendering with revolutionary weapons (i.e. the atomic bomb). Dropping atomic bombs‚ Little Boy and Fat Man‚ on Hiroshima and Nagasaki was legitimate and necessary to defeat Japan because it was the quickest and most effective option to induce Japan to surrender‚ prevent further destruction of the Japanese mainland
