Binding Energy Carbon

Introduction to binding energy of carbon:

To begin with a discussion on binding energy of carbon, let us begin with the atom of carbon. Carbon atom has six electrons, six neutrons and six protons. A carbon atom combines with another carbon atom by forming a bond between them. These bonds are necessary for the existence of carbon molecule and for different chemical reactions. It is one of the elements, which is fond the most naturally. The quantity of energy that is required to haul the proton and neutron apart considerably is known as binding energy. Let us study carbon’s binding energy in detail. Having problem with Atomic Mass Carbon keep reading my upcoming posts, i will try to help you.

Description of Binding Energy of Carbon

The distance between the centers of the atoms bonded together is called as the bond length. Bond order is the electron pair number. These electron pairs are shared between the atoms for forming bonds. In case of carbon-carbon bond, the bond order is 2. In order to break the bond between the carbon-carbon bonds, the binding energy between the two atoms needs to be countered. The energy required to break the bond is called bond dissociation energy or bond energy. Generally the bond lengths between the atoms of a particular element remain the same. As the lengths are the same, the bond energy also remains the same.

Studies shows that the shorter the bond length, the higher the binding energy.  The following is a table of different substances, including carbon. Please express your views of this topic Basic Physics Formulas by commenting on blog.

The table gives a comparison of the bond lengths and binding energies of the different elements and molecules of compounds.

Conclusion for Carbon’s Binding Energy

From the discussion made on binding energy of carbon, binding energy of carbon can also be defined as the enthalpy change on a reaction to break the bonds. The binding energy between the carbon atoms exists due to the C-C bond. These are covalent bonds which are formed by equal sharing of electrons.

Marie Curie Radioactivity

Introduction to Marie Curie radioactivity

The study of nuclear physics began when Becquerel discovered radioactivity in 1869, just one year after the discovery of X-rays. He found that accidentally, that an ore containing uranium emits an invisible radiation that can penetrate a black paper wrapper and expose a photographic plate. The rays are called as radioactive rays. Madam Marie Curie and her husband Pierre Curie conducted the most significant investigation in the field of radioactivity. After several years of careful and the laborious chemical separation process on tons of pitchblende, a radioactive ore, the Marie Curie reported the discovery of two previously unknown elements, both of them were radioactive. These were named polonium and radium. Madam Marie Curie was awarded Nobel Prize in 1903 for the discovery of radium. I like to share this Curie Law with you all through my article.

Marie Curie Radioactivity

Radioactivity is the spontaneous phenomenon exhibited by the heavy elements only. It is the property of the heavy elements, which disintegrates itself without being forces by any external agent. The total number of radioactive elements known at present is about 40. The natural elements with atomic number more than 82 are all radioactive, for example, Radium, Thorium, Actinium, Polonium etc. The phenomenon of radioactivity is not affected by pressure, temperature, chemical changes etc. The electrons orbiting around the nucleus are not responsible for the phenomenon of radioactivity.

Laws of Marie Curie Radioactivity

The laws of Marie Curie radioactivity are as follows:

(i) Radioactivity is a spontaneous process, which does not depend upon external factors like temperature, pressure etc.

(ii) During disintegration of an atom, either an alpha particle or a beta particle is emitted. Both of these particles are never emitted simultaneously. At a time, an atom will not emit more than one alpha particle or more than one beta particle.

(iii) The emission of alpha particle from an atom will change it into a new atom whose mass number is reduced by 4 and the atomic number be reduced by 2.

(iv) The emission of beta particle from an atom will change it into a new atom whose mass number remains same and the atomic number be increased by 1.
