Mo\u017eno si mysl\u00edte, \u017ee v be\u017enom \u017eivote nevyu\u017eijete znalosti o at\u00f3moch, alebo o tr\u00e1ven\u00ed. Opak je pravdou. Vezmime si len nov\u00fd fenom\u00e9n. Je u\u017e v\u0161eobecne zn\u00e1me, \u017ee morsk\u00e1 so\u013e je ove\u013ea zdrav\u0161ia ako oby\u010dajn\u00e1 kuchynsk\u00e1 so\u013e \u0165a\u017een\u00e1 v so\u013en\u00fdch baniach. A pre\u010do? Morsk\u00e1 so\u013e \u00fadajne obsahuje menej sod\u00edka a teda nesp\u00f4sobuje vysok\u00fd krvn\u00fd tlak.\t\u00a0\tPre\u010do je to nezmysel?\t\u00a0\tPreto\u017ee vzorec pre so\u013e je NaCl.\u00a0 So\u013e sa jednoducho sklad\u00e1 z jedn\u00e9ho at\u00f3mu sod\u00edka a jedn\u00e9ho at\u00f3mu chl\u00f3ru. Nie je mo\u017en\u00e9, aby so\u013e obsahovala viac sod\u00edka, preto\u017ee toto mno\u017estvo je pevne dan\u00e9 a nemenn\u00e9. Ak by sme hypoteticky chceli zv\u00fd\u0161i\u0165 mno\u017estvo sod\u00edka, alebo chl\u00f3ru, vznikla by \u00faplne in\u00e1 zl\u00fa\u010denina ako so\u013e. Okrem toho, dva at\u00f3my sod\u00edka vlastne ani nie je mo\u017en\u00e9 spoji\u0165 s at\u00f3mom chl\u00f3ru, ke\u010f\u017ee dva sod\u00edky spolu tvoria pr\u00edli\u0161 ve\u013ek\u00fd komplex na ktor\u00fd sa jeden chl\u00f3r ned\u00e1 pripoji\u0165. Okrem toho Na2 m\u00e1 neutr\u00e1lny n\u00e1boj a teda ani keby to ve\u013ekos\u0165 dovo\u013eovala, nie je mo\u017en\u00e9, aby sa prirodzene z\u00e1porne nabit\u00fd at\u00f3m chl\u00f3ru natrvalo pripojil dvom at\u00f3mom sod\u00edka.\t\t\u00a0\tSkr\u00e1tka, so\u013e je so\u013e.
