Question

name teacher: date: q2 chemistry: u4l3.5 lattice structure intro prepwork chemistry prepwork part 1 ionic compound practice 1. for each pair of elements below, draw the lewis dot diagram to represent the ionic compound they would form, write the formula, and then the name. element pair lewis dot diagram of ionic compound formula name lithium & fluorine formula name calcium & nitrogen formula name sodium & nitrogen formula name magnesium & phosphorus formula name *aluminum & chlorine

Explanation:

Step1: Determine charges of elements

Li: +1, F: -1; Ca: +2, N: -3; Na: +1, N: -3; Mg: +2, P: -3; Al: +3, Cl: -1.

Step2: Balance charges for formulas

LiF (1+1-); Ca₃N₂ (3×2+ + 2×3-); Na₃N (3×1+ +1×3-); Mg₃P₂ (3×2+ +2×3-); AlCl₃ (1×3+ +3×1-).

Step3: Name ionic compounds

Cation name + anion name (anion ends with -ide).

Answer:

Element Pair	Lewis Dot Diagram of Ionic Compound	Formula	Name
Calcium & nitrogen	3Ca²⁺ + 2[:N:]³⁻	Ca₃N₂	Calcium nitride
Sodium & nitrogen	3Na⁺ + [:N:]³⁻	Na₃N	Sodium nitride
Magnesium & phosphorus	3Mg²⁺ + 2[:P:]³⁻	Mg₃P₂	Magnesium phosphide
Aluminum & chlorine	Al³⁺ + 3[:Cl:]⁻	AlCl₃	Aluminum chloride
