Crystal Imperfections & Love Flaws
What are the three main types of crystal imperfections?
point defects, line defects, and surface defects
Just like in relationships, materials have limits! This is the maximum stress a material can withstand before breaking.
What is tensile strength?
Which material, commonly used in engineering, is also a symbol of love and durability?
gold
This type of bond forms when atoms share electrons, just like a balanced relationship where both partners contribute equally
What is a covalent bond?
This is the most common crystal structure in metals, with a repeating, organized pattern—just like a well-structured relationship.
What is a face-centered cubic (FCC) structure?
Just like tiny misunderstandings in relationships, these defects involve missing or misplaced atoms in a lattice.
What are point defects?
Some materials return to their original shape after stress, just like a couple overcoming arguments. What is this property called?
What is elasticity?
The strongest natural material on Earth is also used in engagement rings.
What is diamond?
Opposites attract! This type of bond forms when one atom donates electrons to another, similar to a selfless act in love.
What is an ionic bond?
The way atoms are arranged in a solid defines this property, just like compatibility defines a relationship.
What is crystal structure?
In a perfect crystal, atoms are arranged in order. But just like love, imperfections exist! What type of defect involves extra half-planes of atoms disrupting the order?
What is an edge dislocation?
Hard but brittle—like a heart that has been hurt. What kind of material behaves this way?
What is a ceramic?
This metal is known for its flexibility and is often used in making wedding bands.
What is platinum?
This bond occurs in metals, where electrons are free to move, just like an open and communicative relationship.
What is a metallic bond?
When two materials mix at the atomic level to form a single phase, it’s called this—similar to two people blending their personalities in love.
What is a solid solution?
This imperfection is like a long-distance relationship—atoms are missing in a linear manner, causing stress in the crystal structure.
What is a screw dislocation?
Love needs flexibility! Which material property allows metals to be stretched into thin wires?
What is ductility?
Just like a well-designed structure, a strong relationship requires this principle in engineering and love.
What is balance?
This weak secondary bond is like a long-distance relationship—it holds atoms together but is easily broken.
What is a Van der Waals bond?
This defect happens when an atom sits where it doesn’t belong, like an unexpected guest at a Valentine’s Day dinner.
What is an interstitial defect?
Love can sometimes feel like a grain boundary. Why do grain boundaries affect the strength of materials?
What is because they disrupt atomic continuity, making materials stronger but sometimes more brittle
Some materials absorb shocks well—like forgiving hearts. What is this property called?
What is toughness?
This engineering principle ensures that forces are evenly distributed, much like how a good relationship works.
What is stress distribution?
This special bond, often found in water molecules, is strong yet flexible, much like a supportive partnership.
What is a hydrogen bond?
The ability of a metal to change shape under stress without breaking is called this—just like a flexible and adaptable relationship.
What is malleability?
