The nuclide symbol contains the mass number, A, as a superscript to the left of the element's symbol, and the atomic number, Z, as a subscript to the left of the element's symbol, X: Symbolizing a Nuclide Examples: C 12 6 6 protons and 6 neutrons, referred to as carbon twelve, also symbolized C-12 19 C 13 6 6 protons and 7 neutrons, referred to as carbon thirteen, also symbolized C-13 C 14 6 6 protons and 8 neutrons, referred to as carbon fourteen, also symbolized C-14 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 total number of nucleons, that is, protons and neutrons in a nucleus, is equal to Z + N = A, where A is called the atomic mass number.

Nuclide symbol is expressed as above, (where,z is the atomic number and A is the mass number) now, z=total number of protons=11 and a= total number of protons + total number of neutrons= (11+11) or 22

… (a) Sketch, using the axes provided, a graph of neutron number, N, against proton number, Z, for stable nuclei over the range Z = 0 to Z = 80. Show suitable numerical values on the N axis. N increases as Z increases - Graph should pass through N = 10 when Z = 10.

If the nuclide is light, it is usually stable when the number of protons and neutrons are equal or near equal. Write the symbol (in the form _{Z}^{A} \mathrm{X} ) for the nuclide that has 78 neutrons and 53 protons. Join our Discord to get your questions answered by experts, meet other students and be entered to win a PS5! Notice that at low Z, the ratio of neutrons to protons (N : Z) is about 1.0.

The total number of nucleons, that is, protons and neutrons in a nucleus, is equal to Z + N = A, where A is called the atomic mass number. Thus the symbol 1 H refers to the nuclide of hydrogen with a single proton as nucleus. 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.

Atomic number (proton number) plus neutron number equals mass number: Z + N = A.The difference between the neutron number and the atomic number is known as the neutron excess: D = N - Z = A - 2Z.. Neutron number is rarely written explicitly in nuclide symbol notation, but appears as a subscript to the right of the element symbol. In order of increasing explicitness and decreasing frequency of

Notice that at low Z, the ratio of neutrons to protons (N : Z) is about 1.0. Above Z = 20, stable nuclides have more neutrons than protons (N/Z > 1.0). At higher Zs, the stability of nuclei tends toward neutron-rich nuclides. It has been observed that nuclei with 2, 8, 20, 28, 50, 82, or 126 nucleons (protons and neutrons combined) are stable.

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? Atomic number (proton number) plus neutron number equals mass number: Z + N = A. The difference between the neutron number and the atomic number is known as the neutron excess: D = N - Z = A - 2Z. Neutron number is rarely written explicitly in nuclide symbol notation, but appears as a subscript to the right of the element Subatomic particles of the nucleus (protons and neutrons) are called nucleons. A nuclide is an atom with a particular number of protons and neutrons.
