Chapter 43: Q6Q (page 1330)

To make the newly discovered, very large elements of the periodic table, researchers shoot a medium-size nucleus at a large nucleus. Sometimes a projectile nucleus and a target nucleus fuse to form one of the very large elements. In such a fusion, is the mass of the product greater than or less than the sum of the masses of the projectile and target nuclei?

Short Answer

Expert verified

The mass of the product is always less than the sum of masses of the projectile in nuclear fusion.

Step by step solution

01

Nuclear Fusion

Nuclear fusion is the process in which two lighter nuclei of different or same atoms form a heavier nucleus by combination is called nuclear fusion. A huge amount of energy is absorbed by lighter nuclei.

02

Whether the mass of the product is greater or less than the sum of masses of the projectile in nuclear fusion

The mass of the product is always less than the sum of masses of the projectile in nuclear fusion because some of the masses of the projectile are converted into energy. The mass of the projectile is converted to energy to form the product atom.

Therefore, the mass of the product is always less than the sum of masses of the projectile in nuclear fusion.

Which of these elements is not “cooked up” by thermonuclear fusion processes in stellar interiors: carbon, silicon, chromium, bromine?

During the Cold War, the Premier of the Soviet Union threatened the United States with 2.0 megaton Pu239warheads. (Each would have yielded the equivalent of an explosion of 2.0 megatons of TNT, where 1 megaton of TNT releases 2.6×1028MeVof energy.) If the plutonium that actually fissioned had been 8.00% of the total mass of the plutonium in such a warhead, what was that total mass?

Calculate the disintegration energy Q for the fission of C52rinto two equal fragments. The masses you will need are
