Nuclear fission and nuclear fusion are reactions that release energy because of the high-powered atomic bonds between the particles in the nucleus. To understand fission and fusion reactions, we must first understand the difference between them. In a fission reaction, a massive nucleus is split in the form of gamma rays, free neutrons and other subatomic particles. In a fusion reaction, two nuclei combine to form a new element that contains more protons in the nucleus (higher atomic number). Those are the basic definitions of the fusion and fission reactions.
The different amount energies released results in different color. This reason is the same reason that different elements have different line spectra. The quantum theory says that a certain amount of energy has be released or absorbed and Bohr 's said the same but with restrictions. The quantum theory would explain the vast differences in energy in color. The reason atoms need heat is because heat gives the atoms energy which causes them to move to an excited and then back to ground state.
two different directions to the spin. He also gave the world a rule to dictate how an electron in an atom would behave. Pauli’s exclusion principal states that, “if an electron has a certain set of quantum numbers then no other electron in that atom can have the same set of quantum numbers.” When 1926 came Erwin Schrödinger another Austrian physicist built upon Einstein and Louis de Broglie’s idea of wave particle duality. He developed a mathematical Equation that related the pattern of electrons with that of waves, he gave his wave mechanics the symbol psi . In 1932 James Chadwick discovered a second particle in the nucleus, he fired alpha particles at beryllium and found that neutrons were released.
Activity: 1. Observe and describe the effect of different wavelengths on speed of electrons emitted. 2. Observe and describe the effect of different levels of intensity on number of electrons emitted. 3.
Some causes cannot be avoided such as the normal aging process and heredity. However, you can modify your lifestyle to avoid developing varicose veins. Jobs that require long periods of sitting or standing can put extra pressure on the heart and veins to keep the blood flowing from the feet back to the heart. Hormonal issues such as pregnancy, menopause and birth control pills may also weaken veins so that they twist and bulge. The lack of physical exercise may also contribute to developing varicose veins.
Nuclear fission can be similar to nuclear fusion for example they both release heat energy. However, in nuclear fusion: • two nuclei must join together • Extremely high temperatures are needed. To develop further: Nuclear fusion is the joining of smaller nuclei to make larger ones. For example; Deuterium and Tritium form to make a bigger and heavier nucleus and Helium releases a lot of energy. Nuclear fusion also happens in stars.. Fission Fission is another word for splitting.
While taking steroid can make you feel stronger it is actually making the muscles grow to quickly which can result in muscle tears from lifting heavy things and the tendons to rupture. And with the skin steroids affect how you look to other people. Meaning it causes red blotchy, greasy skin with acne on the face and back. Stretch marks can also appear due to the skin thinning. (Foegh, Maria 1983) Now taking all that I have told you in account you should understand that taking steroids will cause many effects on the body.
Nuclear energy What is nuclear energy: Nuclear energy is a nuclear power that released by nuclear reaction to generate heat. the energy released. nuclear energy uses fuel made from mined and processed uranium to make steam and generate electricity by two ways. nuclear fusion and nuclear fission. In nuclear fusion, energy is released when atoms are combined or fused together to form a larger atom.
When the nucleus of an atom splits or when two nuclei of different atoms combine, a large amount of energy is released in the form of heat and radiation. Their energy is termed as Nuclear Energy. Nuclear processes are used in order to generate heat or electricity from nuclear energy. These nuclear processes are performed using the earth elements. During these processes the nuclei of atoms either join together which is called fusion or they break apart which is called fission.
Since the patient is given radiopharmaceutical, it may cause allergic reaction. Therefore, the patient must tell the technologist, doctor or nurse before the radiopharmaceutical is given to him/her. However, cases of allergic reactions are very rare (Cain, 2013). The second safety risk issue is radiation. Gamma rays of this system are ionizing radiation that causes changes in body’s molecules.
