This is true because uranium is continuously… Some Conventions. The term "Average Atomic Weight" or simply "Atomic Weight" is commonly used to refer to what is properly called a "relative atomic mass".Atomic Weights are technically dimensionless, because they cannot be determined as absolute values. They were historically calculated from mass ratios (early chemists could say that magnesium atoms have atoms of mass 24.305/15.999 times as 2021-01-27 Atomic Mass, Atomic Number, Isotopes, Physical Science Lesson PowerPoint 1. • The Boron 5 N 7 Br 79.90 amu S Sulfur 32.065 Cs Cesium 132.91 Be Beryllium 9.01 Lead 207.20 Cl 35.45 amu Au 196.97 amu O Oxygen Ir Iridium 192.22 Neon 20.18 10879 82 17 35 No 102 Nobelium Zinc 65.41 30 H Hydrogen 1.01 1 Ca Calcium 20 2019 Name: Date: Student Exploration: Average Atomic Mass Vocabulary: average atomic mass, isotope, mass defect, mass number, mass spectrometer, nuclear binding energy, unified atomic mass unit, weighted average Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1.

The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. The atomic number of lead, Pb, is 82.

Lead is the element with the heaviest stable isotope, 208 Pb. (The more massive 209 Bi, long considered to be stable, actually has a half-life of 2.01×10 19 years.) A total of 43 lead isotopes are now known, including very unstable synthetic species. In its fully ionized state, the isotope 205 Pb also becomes stable.
