Confusing Types of Bonding
Students often confuse electron transfer (ionic bonding) with electron sharing (covalent bonding) when describing chemical reactions.
Fix itTo fix this, clearly differentiate between ionic and covalent bonding: ionic bonding involves the transfer of electrons, while covalent bonding involves the sharing of electrons.
Misclassifying Reaction Types
Students often confuse proton transfer reactions with electron transfer reactions.
Fix itReview the definitions of proton transfer and electron transfer, focusing on the role of protons and electrons in each type of reaction.
Misunderstanding Energy Conservation
Students often think that energy can be created or destroyed during a chemical reaction.
Fix itEmphasize that energy is conserved, meaning it can only change forms but cannot be created or destroyed.
