The Neucleosynthesis Of Light Elements

The light elements were found by nuclear reactions in the stars form from primeval hydrogen and helium.Total mass number and overall charge are conserved in nuclear reactions. A large binding energy signifies a stable nucleus. 

• Energy is released when light nuclei fuse together to give elements of higher atomic number.
• Nuclear reaction is million times more energetic than typical chemical reaction.
• In a balanced nuclear equation , the sum of the mass number of the reactants is equal to the sum of mass number of the products.
• A nucleus of a specific atomic number is known as a nuclide.
• A positron a positive charged, it has a zero mass number and single positive charge.
• When a positron emitted the mass number of the nuclide is remain same but the atomic number decreased by one due to the loss of one positive charge.
• Elements up to 26 were formed inside stars. They are the remnant of nuclear burning.
• ·         α particles are He⁴ atoms which has 2 protons and two electrons.
