Atomic Builder
Touch the atom. Change the charge. Watch identity, isotope, and ion logic respond while Master Alchem keeps the model grounded.

C
Carbon
C has 6 protons, 6 neutrons, and 6 electrons. It is neutral in this configuration.

Atomic number
The proton count defines the element identity.
Mass number
Protons plus neutrons identifies the isotope.
Isotope
Same protons, different neutrons. Chemistry is mostly similar; mass changes.
Ion
Unequal protons and electrons create charge, changing attraction and reactivity.
Mini challenge: build oxygen ion
Set 8 protons, 10 neutrons, and 10 electrons. Can you predict the charge before the panel updates?

Master Alchem's lab note
Identity follows protons. Isotope follows neutrons. Charge follows the difference between protons and electrons.
