The whole idea, one bite at a time
Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.
Malleable vs Ductile
Two words, two shapes
↳ Mould into sheets; Draw into wires.
Non-metal Properties
The opposite team
↳ Dull, brittle, silent, insulating — the non-metal profile.
Metals + Oxygen
Burning through the series
↳ Same reaction, wildly different vigour — the first glimpse of the series.
Amphoteric Oxides (Al₂O₃, ZnO)
The oxides that swing both ways
↳ AZ — Aluminium and Zinc oxides fight on both fronts.
Metals + Water
The temperature ladder
↳ Cold → hot → steam → never: the water test ranks the metals.

Physical Properties of Metals and Non-metals
Lustre, malleability, ductility, conduction, sonority — the metal checklist, the non-metal contrast, and the famous exceptions that examiners love.
- Metals are lustrous (shiny), generally hard, malleable (beaten into sheets), ductile (drawn into wires), good conductors of heat and electri...
- Gold and silver are the MOST MALLEABLE metals; gold alone is the MOST DUCTILE — one gram of it can be drawn into a wire about 2 km long.
- Best heat conductors: silver and copper; poor (relatively): lead and mercury.

Chemical Properties of Metals and the Reactivity Series
How metals react with oxygen, water, acids and each other's salts — building the reactivity series K to Au, with amphoteric oxides, aqua regia and the anodising story.
- Metal + oxygen → metal oxide (generally basic): 2Cu + O₂ → 2CuO (black); 4Al + 3O₂ → 2Al₂O₃.
- Amphoteric oxides — Al₂O₃ and ZnO — react with BOTH acids and bases.
- Na and K burn vigorously in air / catch fire if left open — stored under kerosene; Mg burns with dazzling white flame; Fe filings sparkle; C...

How Metals and Non-metals React: Ionic Bonds
Electron transfer from metal to non-metal, the Na-Cl and Mg-O stories with electron-dot pictures in words, and the four signature properties of ionic compounds.
- Atoms react to reach the stable electron arrangement of the nearest noble gas (complete outer shell — the octet).
- Metals have 1-3 outer electrons and LOSE them, becoming positive ions (CATIONS); non-metals have 5-7 and GAIN electrons, becoming negative i...
- Na (2,8,1) gives its one outer electron to Cl (2,8,7): Na⁺ (2,8) + Cl⁻ (2,8,8) — both now octet-complete.

Extraction of Metals, Corrosion and Alloys
From ore to pure metal — the three extraction zones of the reactivity series, roasting vs calcination, the thermite reaction, electrolytic refining — plus corrosion prevention and the alloy gallery.
- Minerals are naturally occurring metal compounds; an ORE is a mineral from which metal can be extracted profitably; GANGUE is the sand/impur...
- Extraction follows the reactivity series: LOW metals (Hg, Ag, Au) — by heating alone or found free; MIDDLE (Zn, Fe, Pb, Cu) — roast/calcine...
- ROASTING: heating a SULPHIDE ore strongly in EXCESS air → oxide (2ZnS + 3O₂ → 2ZnO + 2SO₂).

216 questions laddered from warm-up to topper-level, each with an explanation. A taste:
Consider these statements about the physical properties of metals. I. Malleability is the ability to be beaten into sheets. II. Ductility is the ability to be drawn into wires. III. Sonority is the ability to ring when struck. IV. Every metal shows all three properties equally well. Which statements are correct?
Intermediate
A I, II and III only
B I and IV only
C II and III only
D All four
Show answer & explanation
I, II and III only
The three definitions are right; the generalisation is not. Gold is far more ductile than lead, and sodium is soft enough to cut with a knife.
One gram of gold can be drawn into a wire about two kilometres long. Which property does this demonstrate, and which metal shares the top of that list?
Advanced
A malleability, in which silver stands first among all metals
B sonority, in which copper stands first among all metals
C conductivity, in which silver stands first among all metals
D ductility, in which gold stands first among all metals
Show answer & explanation
ductility, in which gold stands first among all metals
Drawing into a wire is ductility and gold leads it alone. Gold and silver together lead malleability, which is beating into sheets.
The most ductile metal is:
Beginner
A copper
B gold
C iron
D zinc
Show answer & explanation
gold
1 g of gold → about 2 km of wire.
Which statement best explains why mercury and bromine are both mentioned as exceptions when metals and non-metals are described?
Intermediate
A both are liquids that conduct electricity, unlike other liquids
B both are solids that behave as liquids when warmed slightly
C both are gases at room temperature though they are usually drawn as liquids
D mercury is the one metal that is liquid at room temperature and bromine the one non-metal that is
Show answer & explanation
mercury is the one metal that is liquid at room temperature and bromine the one non-metal that is
Metals are typically solid and non-metals typically not liquid, and these two break the rule from opposite sides. Mercury still conducts; bromine still does not.
