(6) Most nuclei are stable. Consisting of protons and neutrons‚ they are unaffected by chemical reactions and have remained the same since they were formed. However‚ some nuclei are unstable and spontaneously release energy in the form of a Helium nucleus (α Alpha)‚an electron (β Beta) and γ Gamma rays. These nuclei are known as radioactive and it’s not possible to predict when a particular radioactive nucleus will emit this energy but a large number of materials are said to have a ‘half life’

The earth is connected to the universe because all the matter and energy we see today comes from the big bang. The big bang theory is all matter and energy today comes from an explosion called the big bang. There are a lot of questions on the Big Bang and that is why I am here. All the questions you have will be answered in the following paper. All the matter and energy in our universe comes from the Big Bang. In our lab‚ the balloon expanded and the wave length of the wave got bigger. There

a deuterium nucleus‚ which has one proton and one neutron‚ is formed. A neutrino is created‚ too. Then‚ the deuterium nucleus fuses with another proton and forms the nucleus of helium-3‚ with two protons and one neutron‚ during which time a gamma ray photon is released. Finally‚ two helium-3 fuse together and create helium-4 with two protons and two neutrons. 3. How does the Sun manage to maintain an environment in its core that is conducive to nuclear

nuclear fusion reactor‚ but we could be relying on them for power sometime in the next 30 to 40 years. Nuclear Fusion is created by forcing deuterium (D) and tritium (T) together‚ when forced together their nuclei fuse and then break apart to form a helium nucleus and an uncharged neutron. Most of the excess energy is contained in the free neutron. Fusion occurs at a very high temperature (greater than 100 million Kelvin). At this temperature the deuterium and tritium gas mixture becomes a plasma

not-very-luminous celestial body having a mass between 1028 kg and 84 x 1028 kg). A Newborn Star: When a temperature of about 27‚000‚000°F is reached‚ nuclear fusion begins. This is the nuclear reaction in which hydrogen atoms are converted to helium atoms plus energy. This energy (radiation) production prevents further contraction of the star. Young stars emit jets of intense radiation that

Fusion in the sun ‚1 second ‚ 600 million tons of hydrogen are being converted into helium‚ this reaction releases tons amounts of heat and energy. The process of fusion in the sun is known as The proton chain. The sun starts with protons and through a series of steps ‚ it turns into helium. When this is happening something called plasma is being formed. Plasma is being ionized. The sun is so hot. Really hot but all of the heat and light coming from the sun comes from the fusion process happening
