Copper’s electronegativity value = 1.90

Electronegativity measures how strongly an atom attracts electrons in a chemical bond.

Copper’s Pauling electronegativity value (1.90) that explains why copper forms mostly covalent compounds with non-metals rather than purely ionic ones, and why it behaves as a relatively “noble” metal with moderate electron attraction.

Moderate electron attraction enables copper reactive enough for useful chemistry and biology, but stable enough to avoid extremes of corrosion, toxicity, or inertness. This balance underlies its widespread use in technology, industry, and essential life processes.

Comparatively, fluorine is the most electronegative value of 4.0 and very “electron-greedy” (it pulls electrons strongly toward themselves), where toothpastes usually contains.  However, Fluoride-free toothpaste could lower the accumulation of calcium phosphate crystals in the pineal gland.  Then, we could talk with our higher self freely without block.
