Lewis Dot Structures Worksheet - Weebly
Chemical Bonds – Ionic BondsIdentify the Number of Valance Electrons and Draw the Lewis Dot StructureNotes: 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 to illustrate those outer electrons.ElementBohr DiagramGroup Number (PT)# of Valance ElectronsLewis Dot StructureCalciumCarbonHydrogenHeliumOxygenFluorineNeonSodiumAluminumDetermining the Ionic ChargeElementPropertyBefore Making an OctetAfter Making an OctetLielectron config# protons#electronschargeBohr DiagramLewis Dot StructureBeelectron config# protons#electronschargeBohr DiagramLewis Dot StructureBelectron config# protons#electronschargeBohr DiagramLewis Dot StructureSkip CarbonNelectron config# protons#electronschargeBohr DiagramLewis Dot StructureOelectron config# protons#electronschargeBohr DiagramLewis Dot StructureFelectron config# protons#electronschargeBohr DiagramLewis Dot StructureNeelectron config# protons#electronschargeBohr DiagramLewis Dot Making Ions – Ionic Bonds are made of Ions. A strong understanding of Ions is needed.Notes: Remember that Metals tend to lose their electrons, falling back to their inner octet, becoming smaller, forming positive “cations”. Nonmetals tend to gain electrons, filling up their current energy levels, becoming larger, forming negative “anions”. Complete the chart below.ElementLewis Dot # of Valance e-Gain/Lose ___ e-Valance ChargeNa1L 1+1BeClSAlNeKNOCaPBMgLewis Dot, Formula Unit & Naming Practice Sheet Notes: An ionic bond is an attraction of a cation for an anion resulting from the transfer of electrons. Remember, the smaller nonmetals are more electronegative and pull the electrons close, away from the larger, less electronegative metals. When naming ionic compounds, the Metal is named first, followed by the nonmetal with an –ide ending. Ex. Sodium Fluorine becomes Sodium Fluoride.Formula Unit: Lowest whole number ratio of elements in the compound. Ex. Ca3N21.

Identify the charges = Mg2+ F1Cross the Charges, Mg2+ F1 = Mg1F2If the subscript is a 1 it does not need to be written. If there is a common subscript such as 2 as in Mg2O2, reduce it to Mg1O1 which is also MgO.Write Formula Unit For the Below Ionic CompoundsNameCation (+)Anion (-)Formula1Sodium ChlorideNa1+Cl1-Na1+1Cl1-1 = NaCl2Aluminum ChlorideAl3+Cl1-3Aluminum Phosphide4Magnesium Oxide5Cesium Fluoride6Strontium Nitride7Lithium Sulfide8Calcium Chloride9Sodium Bromide10Beryllium Iodide11Strontium Fluoride12Aluminum Fluoride13Potassium Nitride14Sodium Sulfide15Lithium Oxide16Calcium OxidePolyatomic Ions WSAmmonium (NH4)1+Carbonate (CO3)2-Chromate (CrO4)2-Dichromate (Cr2O7)2-Hydroxide (OH)1-Nitrate (NO3)1-Nitrite (NO2)1-Sulfate (SO4)2-Sulfite (SO3)2-Phosphate (PO4)3-Write the NAME of each of the following compounds.(NH4)Cl _______________________________Be(SO4) _______________________________(NH4)3N ______________________________MgCl2 ______________________________NH4(NO3)______________________________Sr3(PO4)2 _____________________________Zn(CrO4)2 _____________________________K2(Cr2O7) ______________________________Ga(ClO3)3 ____________________________Cu(OH) ***______________________________(NH4)3(PO4)___________________________Fe(SO4)_____________________________Mg(NO3)2___________________________(NH4)NO2 ____________________________Na2(Cr2O7)____________________________Na(OH) ______________________________Write the CHEMICAL FORMULA for each of the given NAMES…………cross chargescalcium carbonate Ca2+ (CO3)2- = Ca2(CO3)2 = CaCO3barium nitrate_______________________________ = _______________________________ammonium sulfate _______________________________ = _______________________________aluminum hydroxide ______________________________ = ________________________________calcium phosphate_______________________________ = _______________________________cesium nitrate _______________________________ = _______________________________sodium nitrite _______________________________ = _______________________________calcium sulfate_______________________________ = _______________________________beryllium sulfate_______________________________ = _______________________________sodium carbonate_______________________________ = _______________________________magnesium phosphate_____________________________ = _______________________________calcium phosphate_______________________________ = _______________________________Variable Charge CationsNotes: Some cations can have many charges, they are known as variable charge cationsIt is important to note the charge of the cation when naming the ionic compoundEx: Tin (VI) Oxide….where VI is the charge on tin.Draw SnO3 instead as a picture of Atoms:Total Charge on Oxygen = -6Total Charge on Tin = +6Individual Charge on Tin = +6Name of Compound = Tin (VI) OxideDraw Au3N as a picture of Atoms: Name of Compound = ______________Draw Sn2O3 instead as a picture of Atom Name of Compound = ________________Draw Ag1O3 instead as a picture of AtomName of Compound = ________________What is the name of SnO3? Tin Oxide = Wrong AnswerSince tin has more than once charge, the charge needs to be determined so it can be included in the name.The charge on tin was calculated to be +6, therefore the +6 is included in the naming of the compound. Once again, this is only done with metals with more than one charge.What is the name of Sn2O3? What is the name of Cu N?What is the name of Au3N?
