Lattice Energy

What is a cation?

• positive ion
• Neutral atom
• Two additional protons
• negative ion

Which of these combinations is an ionic compound made of?

• Metal and Metal
• Nonmetal and Nonmetal
• Metal and Nonmetal
• Cation and Cation

Which has a greater lattice energy: MgF₂ SrF_{2 .} Why? 

• MgF₂ because greater magnitude of charge
• MgF₂ because of shorter distance
• SrF₂ because of greater magnitude of charge
• SrF₂ because of greater distance

Which ionic compound has a greater distance between ions?

• NaCl
• LiF
• KBr

Which ionic compound has bonds with a greater magnitude of charge?

• LiF
• BeF₂
• BeO
• Li₂O

Which ionic compound has a weaker ionic bond strength?

• MgS because it of the magnitude of charge
• MgS because of the distance
• Na₂S because of the magnitude of charge
• Na₂S because of the distance

When comparing the lattice energy among ionic compounds, what are the two things to consider?

• Magnitude of charge and Distance
• Protons and electrons
• Shells and total valence electrons
• Its random

How do we determine the distance between ions when evaluating lattice energy and bond strength?

• Add the shells
• Multiply the shells
• Add the valence
• Add the charge
