Simulation – build isotope, Atomic number and mass number

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 […]
