Chemical Bonds-lonic Bonds Identify the Number of Valance Electrons and Draw the Lewis Dot Structure

Chemical Bonds-lonic Bonds Identify the Number of Valance Electrons and Draw the Lewis Dot Structure Notes: Scientists use Lewis Dot Structures to show the valance electrons of an element as dots Since bonding involves the valance shell electrons only, it is only necessary electrons to illustrate those outer Group of Valance Number (PT) Electrons Element Lewis Dot Structure Bohr DiagramN Calcium Carbon Hydrogen Helium Oxygen Fluorine Neon Sodium Aluminum Determining the lonic Charge Element Property Before Making an Octet After Making an Octet electron config # protons electrons charge Bohr

Nonmetals tend to gain electrons, filling up their current energy levels, becoming larger, forming negative “anions”. Complete the chart below | Gain/Lose-e- 1 Valance Charge Element Lewis Dot # of Valance e. +1 L1 Na Be ci Al Ne 0 Mg Lewis Dot, Formula Unit & Naming Practice Sheet Notes: s an attraction of a cation for an anion resulting from the transfer of electrons er, the smaller nonmetals are more electronegative and pull the electrons close, away from the larger, less electronegative metals naming ionic compounds, the Metal is named first, followed by the nonmetal with an-ide ending. Ex. Sodium Fluorine becomes Sodium Fluoride 3. Formula Unit: Lowest whole number ratio of elements in the compound. Ex. Ca,N 1. Draw the Lewis Structure for Mg & Cl 2.
