CHEM 4005 Lecture Notes - Lecture 1: Electronvolt, Electron Rest Mass, Unified Atomic Mass Unit
Document Summary
The age of the universe is probably the origin of the universe. Big bang the debris of supernova explosions that occurred before the solar system came into being. The elements heavier than the hydrogen and helium of which the planets are composed probably came from together with the sun. It is most likely that the planets, satellites, and other members of the solar system were formed the conversion of hydrogen to helium. The sun"s energy comes from (atomic numberproton mass) + (mass numberneutron mass)+(electron number*electron mass) = nucleus mass. Calculate the binding energy per nucleon (in units of mev) for be for which the atomic mass is. Particle masses in amu are : proton =1. 007277, neutrons = 1. 008665, electron = Is the mass number is the sum of protons and electrons in an atom correct. A heavy nucleus is fragmented into lighter nucleus. What is true about tin-118 and calcium-40 applies to sub-microscopic particles such as electrons, protons, and neutrons.
