Also referred to as pleural effusion or ' fluid on lungs ', the condition is commonly diagnosed among TB patients. Normally, there is a small amount of fluid surrounding the lungs but in TB there is bacterial growth in the fluid filled space between the chest wall and the lungs.
Following are the equations of several nuclear reactions that have important roles in the history of nuclear chemistry: 1  The first naturally occurring unstable element that was isolated, polonium, was discovered by the Polish scientist Marie Curie and her husband Pierre in 1898. It decays, emitting Î± particles:
A set of nuclides with equal proton number (atomic number), i.e., of the same chemical element but different neutron numbers, are called isotopes of the element. Particular nuclides are still often loosely called isotopes, but the term nuclide is the correct one in general (i.e., when Z is not fixed).he majority of stable nuclides are even-protonâeven-neutron, where all numbers Z, N, and A are even. The odd-A stable nuclides are divided (roughly evenly) into odd-protonâeven-neutron, and even-protonâodd-neutron nuclides. Odd-protonâodd-neutron nuclides (and nuclei) are the least common.
