Advanced Atom Builder
Construct any element, isotope, or ion and connect particle counts to chemical identity.
Explorer modeBuild elements 1–18 with guided particle controls.

Pink = proton · purple = neutron · blue = electron
OOxygen-16Atomic number 8 · Mass number 16Neutral atomShells: 2, 6
Notice: The number of protons fixes the element. Neutrons change its isotope, while gaining or losing electrons creates an ion.
Guided challenge

Gas Laws
Investigate pressure, volume and temperature, holding the other variables constant.
Ideal gas model. Each investigation shows what is held constant. Particle dots are representative; their size is not to scale.

|---|
Use kelvin in gas calculations. Real gases depart from this model, especially at high pressure or low temperature.
Check your understanding
At constant temperature, a gas at 1.20 atm occupies 4.00 L. What is its pressure at 2.00 L?
Acids, Bases & pH
Explore how acid strength, concentration and dilution affect an aqueous solution.
AcidicNeutral at 25 °CBasic
Indicator colour is illustrative, not the actual colour of the solution.
All calculations are at 25 °C with Kᴡ = 1.0 × 10⁻¹⁴. Default weak acid Kₐ = 1.8 × 10⁻⁵; adjustable in Advanced. This dilute-solution model uses concentrations in place of activities. Advanced mode includes a separate strong acid–strong base titration.
Check your understanding
An aqueous solution at 25 °C has [H₃O⁺] = 1.0 × 10⁻³ mol/L. What is its pH?

From secant to tangent
Predict, investigate and explain your reasoning.
About 15 minutes · Preparation: functions and slope. The gold secant passes through P and Q. The dashed teal tangent shows the limiting slope when it exists. The graph rescales to keep P and Q visible; use the axis labels when comparing investigations.
Guided investigation
- For x² at a = 1, reduce h from both sides. What slope is approached?
- Set h = 0. Why is the secant formula undefined even when the derivative exists?
- For |x| at a = 0, compare positive and negative h. Do the slopes agree?
Transform the plane
Predict, investigate and explain your reasoning.
About 20 minutes · Preparation: coordinates and vectors. With column vectors, columns show the images of e₁ and e₂. Apply A first, then B: the combined matrix is BA.
Grey: original grid · plum: transformed grid · gold: unit square · red: e₁ image · teal: e₂ image. Parts outside the viewport are clipped.
Progress blends coordinates from I to BA. Intermediate frames are not repeated applications or a physical rotation.
Guided investigation
- Choose shear: why does the area stay the same?
- Choose reflection: what does a negative determinant tell you?
- Collapse the plane: connect determinant zero to lost dimensions.
- Compare a shear followed by rotation with rotation followed by a shear, using the matrix entries.
