Matter in your table
Your recalled elements connect into familiar matter.
These are constituent-element matches, not instructions for mixing elements. Ratios, bonds, structure, and reaction conditions decide what matter actually forms.
Element map · dotted links show shared membership, not chemical bonds Your table contains caffeine’s four elements.
Every atom in caffeine is carbon, hydrogen, nitrogen, or oxygen. The subscripts show how many of each occur in one molecule.
WaterH₂O Hydrogen peroxideH₂O₂ Same elements. One extra oxygen. Very different matter.
Water and hydrogen peroxide contain only hydrogen and oxygen, but their atom counts and O–O bonding differ. Element membership alone does not determine a substance.
Carbon monoxideCO Carbon dioxideCO₂ The same two elements can draw two different gases.
Carbon monoxide and carbon dioxide use the same element set in different ratios and structures: CO versus CO₂.
One element away
Magnesium would complete the element set for C₅₅H₇₂MgN₄O₅.
