nuclide, , also called nuclear species, species of atom as characterized by the number of protons, the number of neutrons, and the energy state of the nucleus. A nuclide is thus characterized by the mass number ( A ) and the atomic number ( Z ).

Write its nuclide symbol in the form of AX Z . Write two other ways to represent this nuclide. Solution Because this nuclide has 26 protons, its atomic number, Z, is 26, identifying the element as iron, Fe. Exercise 16.1 – Nuclide Symbols: One of the nuclides used in radiation therapy for the treatment of cancer has 39 protons and 51 neutrons. Write its nuclide symbol in the form of A Z X. Write two other ways to represent this nuclide. (Objs 2, 3, & 4) Because this nuclide has 39 protons, its atomic number, Z, is 39. This identifies the Most stable nuclides have both even Z and even N called "even-even" nuclides. We can understand this in terms of Pauli's exclusion principle.

Kohman defined nuclide as a "species of atom characterized by the constitution of its nucleus" containing a certain number of neutrons and protons. The term thus originally focused on the nucleus. Nuclides are commonly expressed in the form A/Z X, where A denotes the total number of protons and neutrons, Z represents the number of protons, and the difference between A and Z is the number of neutrons. Thus 37/17 Cl signifies chlorine-37.

the mass number of the atom The atomic number, Z, is given by the number of protons present inside the nucleus, so you can say that your nuclide has an atomic number equal to 92. The mass number, A, is given by the number of protons and neutrons present inside the nucleus. color (blue) (ul (color (black) (A = Z + "no. of neutrons")))

Describe nuclear structure in terms of protons, neutrons, and electrons; Calculate When referring to a single type of nucleus, we often use the term nuclide and

Each nuclide is denoted by chemical symbol of the element (this specifies Z) with the atomic mass number as superscript. Hydrogen (H), for example , consist of one electron and one proton. The number of neutrons in a nucleus is known as the neutron number and is given the symbol N . The nuclide of thorium that contains 1.5 times as many neutrons as protons. Z = A = N = For example: iron-56 has 30 neutrons and 26 protons, an n:p ratio of 1.15, whereas the stable nuclide lead-207 has 125 neutrons and 82 protons, an n:p ratio equal to 1.52. This is because larger nuclei have more proton-proton repulsions, and require larger numbers of neutrons to provide compensating strong forces to overcome these electrostatic repulsions and hold the nucleus together. Nuclides (X) are the nuclei of atoms of a specific isotope.

Determine the number of protons, neutrons, & nucleons for this nuclide. 40 Z = (No Response) N = (No Response) A = (No Response) Part 2: Strong Nuclear Force The strong nuclear force acts between which pairs of particles? To calculate the binding energy we use the formula Z (m p + m e) + N m n − m nuclide where Z denotes the number of protons in the nuclides and N their number of neutrons. We take m p = (938.2720813±0.0000058) MeV, m e = (0.5109989461±0.000000003) MeV and m n = (939.5654133 ± 0000058) MeV. Subatomic particles of the nucleus (protons and neutrons) are called nucleons.

3.2. Neutron to proton ratio If a graph is made (Fig. 3.1)1 of the relation of the number of neutrons to the number of protons in the known stable nuclei, we find that in the light elements stability is achieved when the number of neutrons and protons are approximately equal (N = Z). However, with
