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.

  1. CaCO₃COCa
    Element map · dotted links show shared membership, not chemical bonds

    Calcium, carbon, and oxygen put limestone on your map.

    Calcium carbonate is the principal chemical constituent of limestone and has the formula CaCO₃.

    PubChem: calcium carbonate

  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.

    PubChem: sodium chloride

  3. NaHCO₃HCONa
    Element map · dotted links show shared membership, not chemical bonds
