    Weak Nuclear Force

    • 1139 Words
    • 5 Pages

    Atomic nuclei consist of protons and neutrons‚ which have a positive or negative charge. Electric forces are repulsive between similar charges‚ so there must be a force much stronger than electromagnetism keeping them together. This force is called the Strong Nuclear Force‚ and it is about a hundred times stronger than the electromagnetic force. Its strength allows it to hold a nucleus together‚ despite the desire of the electromagnetic force to thrust it apart. Despite its relative strength‚ the

Now‚ let’s look at an atom of carbon (Figure 7). The nucleus of the carbon atom contains six protons and six neutrons. Six electrons orbit the nucleus. Now‚ look more closely at the electrons. Note that the electrons orbit the nucleus in two rings‚ or shells. The inner shell 8 Nature of Electricity 47P 61N 29P 35N Single electron in outermost

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

    over 90o their results revealed the presence of atomic nucleus and led to Rutherfords atomic model.3 FORCE OF THE NUCLEUS The strong nuclear force is an attractive force that acts between all nucleus protons and neutrons alike. Thus protons attract each other via force at the same time they repel each other via the electric force‚ nuclei are bound together by the residual strong force‚ the Mesidual strongforce is minor medium of the strong force which

    Matthew Rose Mr. Schwartz Chemistry 8 March 2011 Ernest Rutherford Ernest Rutherford was one of the most famous physicists of the early 20th century. He won the Nobel Prize in chemistry in 1908 for his work on atomic emissions and his contributions that led to the discovery of atomic fission. Ernest Rutherford was born in Nelson‚ New Zealand on August 30‚ 1871. His father was James Rutherford and his Mother was Martha Thompson. His father was a wheelwright‚ a person who builds and repairs

    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

    nuclear force‚ also called the strong interaction. This force acts against the forces of repulsion of protons and binds neutrons and protons to contain them inside the atomic nuclei. This is how the nucleus of the atom is formed. The force is so strong that the minute particle that carries the force is called “gluon‚” which is means “glue” in Latin. The strength of this force is very particular. The protons and electrons are sensitive and have to be specifically arranged and a have the right distance apart

The electron is by far the least massive of these particles at 9.11×10−31 kg‚ with a negative electrical charge and a size that is too small to be measured using available techniques.[46] Protons have a positive charge and a mass 1‚836 times that of the electron‚ at 1.6726×10−27 kg‚ although this can be reduced by changes to the energy binding the proton into an atom
