12. When a nuclide is (properly) named in the form [element name]-[number], the number is always the mass number.
The mass number of a nuclide is found by adding together the number of protons and neutrons in the nucleus of the atom. It is represented by the symbol A in the nuclide symbol.
A nuclide is identified by the number of protons in its nucleus, known as the atomic number, and the total number of protons and neutrons, known as the mass number. These two properties determine the unique identity of a specific nuclide.
Nuclide writing is a notation system used to represent a specific nuclide of an element. It includes the chemical symbol, atomic number, and mass number of the nuclide. This notation is helpful for identifying different isotopes of an element.
Mass number of the parent nucleus will be reduced by 4
Any change of the atomic number.

A nuclide symbol represents a specific isotope of an element and consists of the element's chemical symbol, atomic number, and mass number. The chemical symbol is a one- or two-letter abbreviation for an element, the atomic number is the number of protons in the nucleus, and the mass number is the sum of protons and neutrons in the nucleus.

The number of neutrons in a nuclide can be calculated using the formula: [ \text{Number of Neutrons} = \text{Mass Number} - \text{Atomic Number} ] Here, the mass number is the total number of protons and neutrons in the nucleus, while the atomic number represents the number of protons. Thus, subtracting the atomic number from the mass number gives the number of neutrons.
The nuclide symbol for calcium-41 is ^41Ca. This notation indicates the element (Ca for calcium) and the mass number (41) of the isotope.
This is a stable isotope of sulfur: 1616S.
The atomic mass of phosphorous-31 is 30,97376163(20).
The superscript is the atomic mass number, which is the sum of protons and neutrons. The subscript is the atomic number, which is the number of protons. For a hafnium nuclide with 107 neutrons, the superscript would be 180 (107 neutrons + 73 protons) and the subscript would be 73.
