The Atomic Bomb: Effects on Hiroshima and Mankind The nuclear bomb was the most devastating weapon ever created by man. It was developed between 1942 and 1945 during the second World War. The project to build the worlds first atomic weapon was called The Manhattan Project. The nuclear bomb was based on the idea of splitting an atom to create energy‚ this is called fission. Three bombs were created‚ "Trinity"‚ "Little Boy"‚ and "Fat Man". "Trinity" was dropped on a test site in New Mexico on July

October 10‚ 2012 To Whom It May Concern: November 13 & 14 mark this year’s Diwali and New Year’s Celebrations for the Hindu community. Diwali is the largest celebrated holiday for the Hindu community and is an important part of our culture and religious beliefs. Diwali‚ the festival of lights‚ marks the last year of the Hindu calendar and signifies the triumph of good over evil. It is a time of celebration with family and friends‚ and is a time to reflect on the past year and see how we can improve

Effects of the Atomic Bomb Ryan McNall Southern Vermont College In our vast history of events‚ we have learned a lot about radiation. One event in time that had a big effect on what we know about radiation was when the first atomic bomb was dropped on Hiroshima‚ Japan in 1945. This attack started the nuclear warfare age and gave the world an idea of what radiation can do to your body if it is used in the wrong ways. Before the attack on Japan‚ the United

Atoms‚ Molecules and Elements Melissa DuBois Chem 110 September 16‚ 2013 Earl Steven Gurley Atoms‚ Molecules and Elements Atoms are the smallest unit of matter and a group of atoms can form chemical bonds in order to form a molecule. Molecules are groups of two or more atoms that have bound together and are the makings of matter. Elements are a substance that has only one type of atom that make up that element. First we can learn about how halogens and alkali metals are extremely reactive‚ where

Pineda‚ Carlitos Miguel Ponce M. January 9‚ 2013 AIT2A Natural Science 12 ATOM DEVELOPMENT WITH SCIENTISTS INVOLVED 400 B.C. - Democritus’ atomic theory posited that all matter is made up small indestructible units he called atoms. Democritus expanded the idea to state that matter was composed of small particles called "atoms" that could be divided no further. These atoms were all composed of the same primary matter with the only differences between them being their size‚ shape

understanding upon the structure of the atom. Before Rutherford‚ there was a man named Joseph John Thomson who proposed the structure of the atom. He stated that the electrons of the atoms are actually inside the atom‚ and the atom itself is positively charged‚ like a “raisin pudding”. The electrons are scattered all around the atom. He stated that the electrons and the positively charged material cancel each other‚ making it stable. The structure of the atom‚ proposed by Thomson. (J.J Thomson Plum

The Atomic and Nuclear Structure of an Atom The atom has three main components the protons‚ neutrons‚ and electrons. The protons and neutrons make up the nucleus‚ while the electrons are found outside the atom’s nucleus. Each component of an atom has a charge to it. The protons have a positive charge. The electrons have a negative charge‚ and the neutrons have a neutral charge. The atoms also have a charge. For example hydrogen can be negative‚ positive or neutral. These are called
