3.4: Trends in Electron Affinity and Metallic Character
WebPeriodic Trends. The amount of energy released when an electron is added to a neutral atom to form an anion is called electron affinity. Electron affinities are difficult to measure. Electron affinity increases going left … Web2. Define period trends. Answer: Periodic trends are specific patterns in the properties of chemical elements that are revealed in the periodic table of elements. Major periodic trends include electronegativity, ionization energy, electron affinity, atomic radii, ionic radius, metallic character, and chemical reactivity. Explanation: WebNov 23, 2012 · Periodic trends are specific patterns starting certain elemental characteristics (ie.ionization energy) that increase or decrease as you move to a column or row. Periodical trends exist specific design of certain elemental characteristics (ie.ionization energy) ensure increase or decrease how you move along a column or distance. fm facility maintenance linkedin
