Nuclear Fission

Radioactive Decay, Nuclear Fission and Nuclear Fusion When elements undergo radioactive decay the atoms of one element are changed into the atoms of another element when an alpha or beta particle is emitted from an unstable nucleus. When a nucleus disintegrates and emits an alpha particle it is alpha decay, the alpha particle emitted contains two protons and two neutrons which is equivalent to a helium nucleus being released. Alpha decay occurs because there are too many protons, which causes...

Nuclear Energy

Nuclear Energy There are many advantages and disadvantages of using nuclear power. Nuclear power is said to prevent power outages that happen in areas without nuclear power. For an example, if we were using hydroelectricity and the dam suddenly malfunctions, then we won’t have electricity until someone fixes the dam, and that would be difficult if it happened in the middle of the night. However, on the other hand, nuclear power is also considered toxic and it pollutes the Earth with harmful and...

Nuclear Power

Nuclear Power is the best source of energy for the future. In recent years, an increasing number of countries have recognized the potency of nuclear power as a source of energy. Endeavours have been made to proliferate this technology. Nuclear energy is the use of nuclear reactions to release heat which are converted to other forms of energy such as electricity. This essay will argue that nuclear power is the best source of energy in the future. The reasons are that it is a ...

Development of Atomic Theory

is no charge (neutral). He also found the neutron weighted slightly heavier than the proton. * 1939: Lisa Meitner published the first paper about nuclear fission. She predicted the existence of chain reaction, which contributed to the development of the atomic bomb later. * 1941: J Robert Oppenheimer was known as the “father of the nuclear bomb” after he was brought into the atomic bomb project of the US government. One year later he gathered the group of some of the best physicists in the...

Midterm 1 Notes

Fuel cells produce electricity like batteries but are recharged by adding chemicals * Uranium has 20 million Calories per gram * Power is the rate of energy delivery and can be measured in Cal/sec or in watts * 1 hp = 1 kW * Large nuclear plants can create electricity with a power of about 1 GW * Kinetic energy is the energy of motion * To have the same energy as TNT, a rock has to move at about 1.5 miles per second * The rock that hit the earth was moving about 15 miles...

Overview of The Element Niobium

then heated with magnesium in an argon atmosphere. Vanadium is corrosion resistant and is sometimes used to make special tubes and pipes for the chemical industry. Vanadium also does not easily absorb neutrons and has some applications in the nuclear power industry. A thin layer of vanadium is used to bond titanium to steel. Nearly 80% of the vanadium produced is used to make ferrovanadium or as an additive to steel. Ferrovanadium is a strong, shock resistant and corrosion resistant alloy of...

Enrico Fermi

determined by the statistics of the available final states [5]. After this discovery, he changed his career concentration from theoretical physics to nuclear physics. In 1938, Enrico Fermi was awarded the Nobel Prize in Physics "for his demonstrations of the existence of new radioactive elements produced by neutron irradiation and for his related discovery of nuclear reactions brought about by slow neutrons" [6]. After winning a Nobel Prize, Fermi and his wife, Laura, and two children relocated to the United...

Uranium Poem

of nucleus To divide and explode out This starts a chain recation That we like to call fission And it creates tons of energy, Just like a magician. This process is quick; Done with simplicity And it is what we use To make electricity. Called nuclear energy, It is something quite new And is a topic of debate For more then a few When Uranium was discovered Over two hundred years ago The process of nuclear fission We did not yet know Martin Klaproth named it after the planet Discovered around then Never...

Atom Structure Theories

we can never foresee if the consequences will be positive or negative. With any knowledge we gain, we have to trust human ability to distinct what is good and what is bad. [2] James R.
