Neutron number plus atomic number equals atomic mass number: N+Z=A. The difference between the neutron number and the atomic number is known as the neutron excess: D = N – Z = A – 2Z. For stable elements, there is usually a variety of stable isotopes.
Iron is the 26th element in the periodic table and has a symbol of Fe and atomic number of 26. It has an atomic weight of 55.845 and a mass number of 56. Iron has twenty-six protons and thirty neutrons in its nucleus, and twenty-six electrons in four shells.
Phosphorus is found in Group 15 (VA) of the periodic table. The periodic table is a chart that that shows how chemical elements are related to each other. Phosphorus is part of the nitrogen family along with nitrogen, arsenic, antimony, and bismuth. Phosphorus was first discovered in 1669 by German physician Hennig Brand (ca. 1630-92).
Atoms of the same element (i.e., atoms with the same number of protons) with different numbers of neutrons are called isotopes. Most naturally occurring elements exist as isotopes. For example, most hydrogen atoms have a single proton in their nucleus.
