Chemical formulaA precise statement that
tells which elements are in a compound and their
ratios
![Page 18: Structure of Matter Unit Vocabulary. Atomic number The number of protons in an atom’s nucleus](https://reader030.vdocuments.mx/reader030/viewer/2022032605/56649e835503460f94b84c63/html5/thumbnails/18.jpg)
Chemically stableDescribes an atom whose
outer energy level is completely filled with
electrons
![Page 19: Structure of Matter Unit Vocabulary. Atomic number The number of protons in an atom’s nucleus](https://reader030.vdocuments.mx/reader030/viewer/2022032605/56649e835503460f94b84c63/html5/thumbnails/19.jpg)

human tissue or other materials
![Page 20: Structure of Matter Unit Vocabulary. Atomic number The number of protons in an atom’s nucleus](https://reader030.vdocuments.mx/reader030/viewer/2022032605/56649e835503460f94b84c63/html5/thumbnails/20.jpg)
Covalent bondA type of chemical bond formed by atoms when they share electrons, producing molecules
![Page 21: Structure of Matter Unit Vocabulary. Atomic number The number of protons in an atom’s nucleus](https://reader030.vdocuments.mx/reader030/viewer/2022032605/56649e835503460f94b84c63/html5/thumbnails/21.jpg)
Chemical bondThe force that holds together
the atoms in a compound, occurs because atoms of
most elements become more stable by gaining, losing and
sharing electrons
