Question

Describe the stability of nucleus using graph

Answer 1

Explanation:

Nuclear chemistry is the study of reactions that involve changes in nuclear structure. The chapter on atoms, molecules, and ions introduced the basic idea of nuclear structure, that the nucleus of an atom is composed of protons and, with the exception of _1^1\text{H}, neutrons. Recall that the number of protons in the nucleus is called the atomic number (Z) of the element, and the sum of the number of protons and the number of neutrons is the mass number (A). Atoms with the same atomic number but different mass numbers are isotopes of the same element. When referring to a single type of nucleus, we often use the term nuclide and identify it by the notation _\text{Z}^\text{A}\text{X}, where X is the symbol for the element, A is the mass number, and Z is the atomic number (for example, _6^{14}\text{C}). Often a nuclide is referenced by the name of the element followed by a hyphen and the mass number. For example, _6^{14}\text{C} is called “carbon-14.”
