What is one of two or more different forms of an element? Choose the electron configurations that are possible from among the following. This gain or loss of energy is due to the phenomena that occur at atomic level. 1. DOC Electron Configuration Practice Worksheet - Texas A&M University How do the masses of the proton and the neutron compare to the mass of the electron? If your periodic table doesnt agree with this, your answers for elements near the f-orbitals may be slightly different. The physical and chemical properties of metals and nonmetals differ from each other. A: Br and Cl have the similar properties like Fluorine. No. Mg =. B = Iron (Fe) The contributions of J. J.
