WebNonmetal. There is no precise definition of a nonmetal; which elements are counted as such varies. In chemistry, a nonmetal (or non-metal) is a chemical element that generally lacks a predominance of metallic properties; they range from colorless gases (like hydrogen) to shiny solids (like carbon, as graphite ). WebWhen nonmetals gain electrons, the energy change is usually negative because they give off energy to form an anion (exothermic process); thus, the electron affinity will be negative.Nonmetals have a greater electron affinity than metals because of their atomic structures: first, nonmetals have more valence electrons than metals do, thus it is easier … fhft health roster https://bankcollab.com

WebAcetylene, C2H2, is a highly reactive, commercially important hydrocarbon. Its reactivity is related to its triple bond between carbon atoms and, as a consequence, its high positive free energy of formation. Because of its explosive nature, long distance shipping or pressurized storage is not recommended. Thus acetylene is generally used as it is … WebCa vs. Mg and Fe vs. Cu. 1. Down a group, reactivity increases because there is a decrease in ionization energy (i.e. it takes less energy to remove a Ca valence electron than an Mg valence electron) 2. Across a period, reactivity decreases based on the valence electron shell configuration of Fe vs. Cu. department of health viera fl
