SpecEnvoy Chemistry

Interactive, animated labs that make chemistry make sense — from Grade 10 atoms to first-year molecular shapes. Real data, plain-English explanations, nothing to install, nothing tracked.

A

Atoms & the Periodic Table

what everything is made of
Spotlight
The Elements
Interactive periodic table
Tap any of 118 elements — watch its atom spin and see how it powers the modern economy, from silicon chips to rare-earth magnets. Colour the table by mass, electronegativity, melting point or density.
Open the table →
Atom Builder
Protons · neutrons · electrons
Build any atom from scratch. Add protons to pick the element, neutrons for the isotope, electrons for the ion — and watch a live Bohr atom rearrange its shells.

B

Bonds & Molecules

how atoms join, and the shapes they make
Molecule Lab
3D shapes · VSEPR · polarity
Spin real molecules in 3D. See why water is bent, methane is a tetrahedron and CO₂ is linear — with bond angles, polarity and a gallery of real structures like caffeine, built from public-domain data.

C

Reactions & the Mole

what happens when substances change
Equation Balancer
Balance & classify reactions
Nudge the coefficients and watch the atom tally even out, auto-solve any reaction, see the atoms conserved as coloured molecules, and learn the five reaction types.

D

Matter & Energy

gases, heat, rates and equilibrium
Gas & States Lab
Particle sim · PV=nRT · phases
A live box of molecules. Squeeze the volume, heat the gas, add more — and watch the pressure answer back (Boyle, Charles, PV=nRT). Then heat a substance from solid to liquid to gas.
