Simulation of energy levels of an atom – absorption and emission

Atomic structure, Atomic structure and periodic Table, Chemistry, Particle model of matter, Physics, Science /

Simulation of Energy levels to demonstrate that: “The electron arrangements may change with the absorption of electromagnetic radiation (move further from the nucleus; a higher energy level) or by the emission of electromagnetic radiation (move closer to the nucleus; a lower energy level).” What the simulation does The simulation models the hydrogen atom using the Bohr model […]

Simulation Description: build Isotope, Atomic number and Mass number Isotope Builder — Simulation Students drag protons and neutrons into a nucleus. The element is identified live by proton count, and the isotope name (e.g. Carbon-14) updates instantly as neutrons are added. The same element with different neutron counts visually demonstrates what an isotope is. Class

Simulation Description: Atomic number and Mass number Mass Number & Atomic Number — Simulation Two sliders let students adjust protons (1–18) and neutrons (0–22). The screen updates instantly showing the element symbol and name on a periodic-table-style tile, the live equation A = Z + N, and a colour-split bar showing the proton/neutron ratio in
