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.

    You recalled chlorophyll’s entire elemental alphabet.

    Carbon, hydrogen, nitrogen, oxygen, and magnesium are every kind of atom present in chlorophyll a. This is a composition map, not a synthesis recipe.

    PubChem: chlorophyll a

  2. Na+Cl−
    Ionic pairNaCl

    You named both sides of table salt.

    Sodium chloride is an ionic solid with sodium and chloride ions in a 1:1 ratio. The dotted link is ionic attraction, not a covalent bond.
