Metallic Bonding
What is the arrangement of atoms in a metallic lattice?
What gives metals their shiny “bling” look and lets them conduct electricity?
I’m the “positive guy” in chemistry—formed when atoms lose their cool (electrons). Who am I?
I’m the group of metals that always carry a single backpack of charge. Which group am I?
Cation
Group 1 (+1 charge)
I’m the bond where atoms don’t fight over electrons—they share them like best friends. What am I?
I’m found mostly in nonmetals, and I’m stronger than a handshake. What type of bond am I?
Covalent bond
I’m the tiniest piece of an element that still exists.
I’m the detective tool that makes pigments race up paper to reveal their secrets.
Atom
Paper Chromatography
I am a crowd with no names,
I wander freely through atomic games.
I glue the ions, yet let them slide,
Without me, metals would crumble inside.
What am I?
What is a common but incorrect belief about how metals conduct electricity?
The delocalised electrons.
Metals conduct electricity because their atoms move around.
What nickname describes the swarm of electrons moving freely in metals?
Who are the “dance partners” that keep the metallic lattice together?
The “sea of electrons
Positive metal ions and negative electrons.
I’m the breath of life, but in ionic form I carry two negative suitcases. Who am I?
I’m the salty duo that balances perfectly—one small, one big, but together we’re tasty. What am I?
O²⁻
Sodium chloride (NaCl)?
I’m the invisible attraction between positive nuclei and shared negative electrons. What am I describing?
Draw me with dots and crosses—I’m the simplest molecule, just two atoms holding hands. Who am I?
electrostatic attraction in covalent bonds
hydrogen (H₂)
Evaporate me, cool me down, and watch sparkling solids grow. What am I?
Heat me up and I’ll give you fresh water from salty solution.
Crystallisation
Simple Distilation
I’m unseen but mighty,
I pull opposites tightly.
Without me, crystals crumble,
Guess my name before you stumble!
“Ionic bonds are formed because atoms want to have full outer shells.”
True or False?
Electrostatic attraction.
False.
Atoms don’t “want” anything—this is just a model we use to explain stability. Ionic bonds actually form because of electrostatic attraction between positively and negatively charged ions
What invisible force acts like glue between metal ions and electrons?
What explains why metals can be hammered into sheets or stretched into wires without breaking?
Strong electrostatic attraction.
Layers of atoms sliding over each other.
I’m the “odd one out”—a positive ion made of more than one atom, often mistaken for a molecule. Who am I?
I’m solid as a rock, but when melted or dissolved, I suddenly light up the room. What property am I showing?
NH₄⁺
electrical conductivity
I’m a molecule that’s small and simple, but I refuse to conduct electricity. Why?
I’m a liquid at room temperature, but my cousin with a bigger molecular mass boils at a much higher temperature. Why?
Because small molecules have no overall charge and no free electrons.
Larger molecules have stronger intermolecular forces, so more energy is needed to separate them.
I’m the sneaky math trick that makes you juggle percentages and masses just to figure out how heavy an element really is.
I’m the chemistry nightclub where molecules with different boiling points leave at different floors of the party tower.
calculating relative atomic mass (Ar) from isotopic abundances
fractional distillation?
I’m strong inside but weak between,
I make gases, liquids, and solids unseen.
Break my bonds and you’ll need great might,
But melt me, and it’s forces between you fight.
Graphite is soft because its covalent bonds are weak.” True or False? Explain
Covalent bonding with weak intermolecular forces.
False.
Graphite’s covalent bonds within layers are very strong. It’s soft because the layers slide over each other due to weak forces between them, not because the covalent bonds are weak.
What property of metals comes from their super-strong metallic bonds?
Why can metals conduct heat so efficiently, almost like “thermal highways”?
High melting and boiling points.
Delocalised electrons carry energy.
I’m made of aluminum and oxygen, but my formula looks like a math puzzle. Solve me!
I’m the invisible glue that holds opposites together in a giant crystal dance. What am I?
Al₂O₃
electrostatic attractions
I’m a dot-and-cross diagram with two double bonds—carbon in the middle, oxygen on each side. Who am I?
I’m carbon too, but I slip and slide in layers, and I can even conduct electricity. Who am I?
carbon dioxide (CO₂)
graphite
I’m the invisible referee who decides how far each pigment runs in the chromatography race—my name is a ratio.
I’m the sneaky ninja particle—you can’t see me, I weigh almost nothing, but I zip around outside the nucleus causing all the chemical drama.
Rf value
Electron
I’m the sneaky formula that tells you how crowded particles are in a solution. Divide moles by volume, and I appear.
True or False: One mole of any gas always occupies 24 dm³, no matter the temperature or pressure.
Concentration
False – gas volume changes with temperature and pressure.
What single feature explains both conductivity and malleability in metals?
What type of bonding is like a “communal potluck” of electrons, unlike ionic bonding’s strict give‑and‑take?
Delocalised electrons shared across the whole lattice.
Metallic bonding is different from ionic bonding.
I’m tougher to melt than table salt because my charges are stronger and my bonds tighter. Who am I compared to NaCl?
I’m a shape-shifter metal—sometimes I’m +2, sometimes +3. Which tricky transition element am I?
aluminum oxide (Al₂O₃)
iron (Fe)
I’m carbon shaped like a soccer ball, discovered first among fullerenes. Who am I?
I’m carbon stretched into long cylinders with incredible strength, useful in nanotechnology. What am I?

“I’m chlorine’s average mass when 75% of me is Cl-35 and 25% is Cl-37.” Calculate Relative Atomic Mass.
“Same element, different number of neutrons—like siblings with different hairstyles.”
35.5
Isotopes
I’m the chemistry accountant: I don’t count money, I count particles. My balance sheet always shows 6.022 x 1023 entries per unit. Who am I?
True or False: If you double the volume of a solution, the concentration also doubles.
Mole
False – doubling the volume actually dilutes the solution, so the concentration decreases.
