Unit 9-1: Ionic Bonding

Imagine Mason and Mia are on a treasure hunt by the ocean. They stumble upon a chest filled with kitchen salt. What is the primary composition of this salt?

• Sodium bicarbonate

• Potassium chloride

• Sodium chloride

• Calcium carbonate

Hey there! Zoe and Olivia are having a debate in their chemistry class. Zoe thinks salt is a covalent compound, but Olivia believes otherwise. Can you help them figure out what type of compound salt really is?

• Covalent compound

• Metallic compound

• Ionic compound

• Molecular compound

Hey there! Hannah and Scarlett are curious about the ocean. They're wondering, which elements are primarily involved in the composition of sea salt?

• Sodium and potassium

• Chlorine and carbon

• Sodium and chlorine

• Magnesium and sulfur

Imagine Rohan and Anika are in a science lab. Rohan decides to drop a piece of sodium into water. What explosive reaction do you expect to see?

• A) It dissolves quietly

• B) It ignites and explodes

• C) It sinks without reaction

• D) It floats and evaporates

Hey there! Ava and Michael are curious about chemistry. They're wondering, what is the nature of chlorine in its pure form?

• A) It is a stable blue liquid

• B) It is a non-reactive gas

• C) It is a greenish-yellow reactive gas

• D) It is a solid metal

Imagine Abigail and Kai are in a science lab, and they come across pure sodium and chlorine. Why should they be cautious around these elements?

• A) They are non-reactive and inert

• B) They are essential nutrients

• C) They are extremely reactive and dangerous

• D) They are rare and valuable

Imagine Rohan is in a science lab and accidentally inhales chlorine gas. What effect does this have on him?

• A) It causes euphoria

• B) It has no significant effect

• C) It attacks the tissues of the lungs, throat, and nose

• D) It improves respiratory function

Imagine David and Zoe are in a science lab, watching sodium and chlorine atoms. How do these dangerous atoms transform into the safe compound sodium chloride?

• By losing electrons and forming positive ions

• By gaining protons and forming neutral atoms

• By sharing electrons and forming covalent bonds

• By absorbing neutrons and becoming isotopes

Ethan, Charlotte, and Aria are curious about how atoms party! How do atoms form ions that then combine to form crystals at this atomic dance?

• By transferring electrons and forming ionic bonds

• By sharing electrons equally among atoms

• By increasing their atomic mass

• By splitting into smaller particles
