Na + Cl → Octet rule: main group (s or p block) atoms or ions tend to be stable when they have 8 valence electrons Na: Na +: about the oxygen atom, this bond angle is “bent” in shape. In the following exercises, you are asked to construct a Lewis dot diagram of each molecule and determine the electron group geometry and molecular shape. You must then use this information to construct a correct orbital overlap sketch for each molecule. The atom is natural when it contains equal numbers of electrons and protons. A negatively charged body contains more electrons than protons.A positively charged body is one which contains fewer electrons than its normal number.A Lewis acid is a chemical species that contains an empty orbital which is capable of accepting an electron pair from a Lewis base to form a Lewis adduct.A Lewis base, then, is any species that has a filled orbital containing an electron pair which is not involved in bonding but may form a dative bond with a Lewis acid to form a Lewis adduct. Often, the number of protons and electrons is not the same, so the atom carries a net positive or negative charge. You can determine the number of electrons in The number of protons of an atom cannot change via any chemical reaction, so you add or subtract electrons to get the correct charge.
Nov 14, 2011 · The second Lewis structure is considered to be the correct one because it is more stable and consistent with the experimental data.
