Nuclear forces have a very short range (about one trillionth of a centimetre) but are comparatively strong (about one million times as strong as the electromagnetic

element‚ each having a different number of neutrons. In a corresponding manner‚ isotopes differ in mass number (or number of nucleons) but never in atomic number.[1] The number of protons (the atomic number) is the same because that is what characterizes a chemical element. For example‚ carbon-12‚ carbon-13 and carbon-14 are three isotopes of the element carbon with mass numbers 12‚ 13 and 14‚ respectively. The atomic number of carbon is 6‚ so the neutron numbers in

approximate values of the scale on each axis. (b) Use your graph to explain why energy is released when a neutron collides with a U nucleus causing fission. (2) (c) Neutrons are released when nuclear fission occurs in U. Some of these neutrons induce further fission‚ others are absorbed without further fission and others escape from the surface of the material. The average number of neutrons released per fission is 2.5‚ of which at least one must produce further fission if a chain reaction is to

The involving mesons without electric charge‚ that it gives exchanges forces between proton & Neutron & also therefore maintains charge in dependence character. It is evident for the nature of the products that neutral mesons decay by strong & weak interaction both. It means that neutral mesons constituents responsible for the electromagnetic interaction

Energy: Nuclear Fusion‚ Hydroelectric‚ and Hydrogen Fuel Cells In today’s world‚ where everyone owns an electronic appliance‚ energy is an extremely valuable resource and in high demand. Though in the past this energy was provided by burning fossil fuels such as coal and natural gas‚ this way of providing energy can’t last much longer due to the dwindling amount of fossil fuels and the damage it causes to the environment. Therefore‚ scientists have been searching for new ways of providing energy

a nucleus‚ which is made up of protons and neutrons. · Protons are positively charged particles. Neutrons have no charge. There is an outer layer made up of negatively charged electrons‚ which keep orbiting the nucleus in a random manner. · The number of protons and electrons are always equal in an atom. Because of this‚ the atom has got a neutral charge. · The protons and electrons weigh more or less equal and the total number of protons and neutrons put together make the atomic weight‚ e.g. if

Cosmic Engine - Research Task 1. Describe how energy can be released from the nuclei of atoms (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

Unit 2 Lesson 3 The kinetic theory of matter explains that matter is made up of particles‚ which are in constant motion resulting in the different states of matter. Matter is made of constantly moving particles‚ which tells us how the matter in solids‚ liquids‚ and gases behaves. When molecules bump into each other‚ they do not gain or lose energy‚ they only transfer it‚ so there is no net energy change (law of the conservation of energy). In a solid‚ molecules vibrate in a fixed position
