D. Roosevelt on the idea of a bomb with a magnificent and tremendous power that can be accessed by breaking into the forces of nuclear fission. At the time‚ Germany‚ too‚ had already begun establishing nuclear bombs. It was crucial for the U.S to be the first to create the nuclear bomb so‚ they could remove power of destruction away from Hitler. Roosevelt had agreed to the idea and so for the next four years the U.S will begin practicing the science of a nuclear bomb. This plan‚ at the time‚ was called

&ATOMIC NUMBER AND MASS NUMBERS After reading this section you will be able to do the following: * Define and determine the atomic number of an atom. * Define and determine the mass number of an atom. What is an atom’s atomic number? The number of protons in the nucleus of an atom determines an element’s atomic number. In other words‚ each element has a unique number that identifies how many protons are in one atom of that element. For example‚ all hydrogen atoms‚ and only hydrogen atoms

In 1803‚ atomic theory was revived by John Dalton a) matter is made up of tiny particles called atoms which cannot be created‚ destroyed or split b) all atoms of one element are identical:- same mass and same chemical properties c) a chemical reaction consists of rearranging atoms from one combination to another. d) When elements combine to form compounds‚ small whole numbers of atoms

Ms. Wilson Chem‚ Blk 10 31 October 2012 Atomic Emission Spectra Lab Atomic spectroscopy is the determination of elemental composition by its electromagnetic or mass spectrum. An arrangement of all wavelengths of electromagnetic radiation is called the spectrum; the plural being spectra. As light passes through a prism‚ the frequencies of light emitted by an element separate into separate lines to give the atomic emission spectrum of the element. There are two spectrums in the lab: the incandescent
