Here is an example of this notation using a carbon isotope that contains six protons and six neutrons in its nucleus. We see a carbon atom represented with an atomic number of 6, showing this atom, like all carbon atoms, has 6 protons in the nucleus. The mass number of 12 shows the nucleus contains a total of 12 protons and neutrons.

2) The Chart of nuclides is organized with number of neutrons along the x axis and number of protons along the y axis. Explain the following terms and how to find them in the map. Use 28Si as a point of reference and give examples of the following: 1. Isotope: Isotopes are nuclides with an equal number of protons, but with a different
Write a nuclide symbol to represent this isotope. How many protons, neutrons and electrons does each of the following ions contain? How many electrons does the particle represented by the symbol 31P3– have? What is the nuclide symbol for carbon-12? The most abundant isotope of antimony has a mass number of 121.
Isotope Notation Chem Worksheet 4-2 Nam Any given element can have more than one isotope. To distinguish between the different isotopes of an atom, the element is named with its mass number, for example lithium-7. Remember that the mass number is the number of protons and neutrons.

the isotope with mass 81. Calculate the relative atomic mass of bromine in this sample. Show your working clearly. The group 7 element bromine was discovered by Balard in 1826. Bromine gets its name from the Greek 'bromos' meaning stench. Bromine consists of a mixture of two isotopes, 35Br and 81Br (a) What is meant by the term isotope?
