Ionization Energy ↑, Atomic Size 11 Metallic Character • For atoms, ionization energy (IE) is the energy required for the complete removal of 1 mol of e 's from 1 mol of gaseous atoms: Atom(g) - - Ion+(g) + e AE = IE, > 0 Increases → higher zeff valence orbitals are at lower E harder to lose e from higher IE→ ↑ lower n, valence orbitals are at er E er to lose e from er IE ↑ IONIZATION ENERGY • Metals tend to lose e 's in their chemical changes. Nonmetals tend to gain e 's in their chemical changes. + lower zeff, Valence orbitals are at huaherE = easier to lose e from =hiaher MC+ ļ higher n, valence orbitals are at er E er to lose e from er MC I Increases METALLIC BEHAVIOR • e s' are easier to lose and harder to add farther from the nucleus! → Recall the valence orbitals trends in size & E to figure the others.

The unit of energy in atomic units is given by O 1E m.eª 16m²sh² 1E₂ = 167²m₂sh² me 1E = 16h² me² 1 E = 167 sh

MEA Naming components of the scientific method In the table below you will find three descriptions of sclentists engaging in activities that are part of the sclentific method. What are the missing words? description missing word? 5 ? After studying the chemical reactions of many compounds made of carbon, August discovers a chemical bonds to other atoms when it forms a compound. that says carbon always forms 4 about the arrangement of elements in the Wolfgang develops a Periodic Table, based on some ideas about how electrons are arranged in the different atoms of different elements. Using equations he develops, he is able to predict the exact arrangement of electrons in many atoms, and from there predict why they are where they are in the Periodic Table. Antoine burns some charcoal, and a very small diamond (!), and makes that the only product of both reactions is a heavy gas the (carbon dioxide). Explanation Check 2021 McGraw Hill LLC.
