Atomic energy is energy produced by atoms. The term originated in 1903 when Ernest Rutherford began to speak of the possibility ofatomic energy.[1] The term was popularized by H. G. Wells in the phrase‚ "splitting the atom"‚ devised at a time prior to the discovery of the nucleus. Atomic energy also may refer to: * Nuclear binding energy‚ the energy required to split a nucleus of an atom * Nuclear potential energy‚ the potential energy of the particles inside an atomic nucleus * Nuclear

The algebraic sum of the currents entering a node is equal to zero. 2. What is the equation for the total current in a parallel circuit? It= I1+I2+I3…. 3. Determine the total current in the following nodes. 1) It= 2mA+4mA+6mA= 0.012x10^-3=12mA 2) I + I1+I3= I2 I= 2mA+4mA= 1mA I= 1mA- 6mA

The test tube with a side pipe was connected with a glass syringe. 3. About 3 cm of magnesium ribbon was measured out using a ruler. 4. The magnesium ribbon was polished using steel wool to remove any coating of oxides as magnesium can be a reactive metal. When magnesium is exposed to oxygen it reacts to form metal oxides. This step is necessary in order to obtain reliable results. 5. The mass of magnesium ribbon was measured and recorded using top pan balance. 6. Step 3‚ 4 and 5 was repeated

product which is Magnesium Metal. Another objective was determining the formula of the compound that results when Magnesium and Oxygen react. Theory: The purpose of this lab was to confirm the chemical formula of magnesium oxide by comparing the masses of pure magnesium solid prior to any reaction and magnesium oxide solid after a reaction between all of the magnesium and oxygen from the air when heated from a Bunsen burner in a crucible. Using molar masses of both magnesium and oxygen‚ an expected

yields about 6000 Kilocalories per square meter per year for animals to eat. These primary producers form the first trophic level. The trees in the deciduous forest shed their leaves in winter. This prevents their branches from being broken by the weight of the snow‚ but also means that they have to grow leaves anew each spring. The trees and shrubs produce flowers‚ seeds‚ and fruits‚ such as wild cherries and persimmons. Many of the shrubs beneath the trees also produce fruit‚ such as huckleberries

Tips on Weight Loss and Weight Management These days‚ many teenagers are very concerned about their weight. Many go on crash diets hoping to be transformed into models with svelte figures. Some‚ who are already slim‚ embark on such diets to become as skinny as Victoria Beckham. The seriousness with which teens tackle weight issues is worrying as the methods they use‚ such as going on crash diets and consuming slimming pills‚ are harmful. This article is therefore written with the aim of giving sensible

Atomic Theory Essay We are first going to talk about Protons‚Neutrons and Electrons. These three elements are a very good example of most things that are in use of gas fumes. It all started when Protons and neutrons where‚ Protons were discovered by Experimenting with discharging tubes. Eventually they found out the rest of the Atoms over time. Which brings me into the word of Orbital. Orbital is a Neutron‚ electron or a proton Going around a single atom with certain amounts of energy levels. Which

My topic is the atomic bomb. Two questions I have are one‚ why did the atomic bomb happen? Two‚ how did the atomic bomb change the world? The sub-topics introduce the Manhattan project. Japan refused to surrender‚ why the United States dropped an atomic bomb on Hiroshima and Nagasaki? The atomic bomb was first used in warfare at Hiroshima and Nagasaki in august 1945‚ and the bomb played a key role in ending World War II. The Atomic bomb created the Manhattan project. The Manhattan
