Carbon
Atomic data, electron configuration and a live Bohr model for the element you selected. Pick another from the table above to update it.
Combine elements.
Watch them react.
Pick 2+ elements (or shelf compounds), then run the reaction — verified reactions are auto-balanced; the rest are predicted.
The balanced outcome
The net synthesis equation, product identity, energy change and what you would observe in the flask.
