alpha decay protons

Neutrons are considered as the best projectile particles to hit the target (uranium) nucleus. The uranium may absorb these neutrons and become 9 2 U 2 3 6 which later splits into two smaller nuclei. In addition two neutrons are released and energy is also released. This process is called a ..

The half-life of 92 U 238 against alpha decay is 4.5 x 109 years. How many disintegrations per second occur in 1 g of 92 U 238 ? Suggested solution: Again, since one k mole of any isotope contains Avogadro's number of atoms, there fore 1 g of 92 U 238 cont..

In 1896, the phenomenon of radioactivity was accidentally discovered by French scientist Henri Becquerel. He was performing experiments with uranium compounds. He accidentally placed a crystal of potassium uranyl sulphate over photographic plate wrapped with usual black paper. On developing the p..

During radioactive emissions, the product formed as a result of the emission of an a - particle followed by the emission of two b - particles is an isotope of the parent elemen..

Radioactive elements can undergo a number of different reactions in the process of forming a stable element. Nuclear fission is one such reaction. Fission means to divide. Elements having atomic numbers greater than 90 can undergo fission. Uranium is one such element. In nuclear fission, the nucle..

The Electric Potential Energy - The electric potential energy of the alpha particle at the distance of closest approach from the nucleus was found to be equal to Potential energy x charge on a partic..
