Since the structure of hair protein nature, from a gentle warming and humid can be modified (denatured). This means that the hair can be stretched up to twice its length, thereby breaking the bonds between the sulfur atoms, being flatter for several hours. Hold hands some hydrogen bonds. ACTIVITY Browse the library of his school book in chemistry Head, author Luis Alfredo Mateus, Belo Horizonte, 1st ed., Ed. UFMG, 2001, p.92-93, the experiment "Invisible Crystals", do the experiment after reading and discussing with a colleague notes, the result obtained, relating - with the considerations brought by the text "What Happens" . The electronic structures provide as much information, the geometry of the molecule, energy, properties, related to the types of chemical bonds. Consequently, the stability of the molecules depends on its energy, which results from the balance between the attractive forces between electrons and nuclei and the repulsion between the nuclei and between electrons. After these discussions you can tell he knows how to give the "rappel of atoms." Then answer: what are the moorings and anchors required for an atom or molecule to arrive safe at the end of the rappel, ie stabilize?

Budući da je struktura kose proteina prirode, na blagoj zatopljenja i vlažne mogu se mijenjati (denaturirani). To znači da kosa može biti rastegnut do dva puta svoje dužine, čime se rješava obveznice između atoma sumpora, ulagivati se za nekoliko sati. Držati za ruke neke obveznice vodika. AKTIVNOST Pregled knjižnicu njegove školske knjige u kemiji šefa, autor Luis Alfredo Mateus, Belo Horizonte, 1. ed., Ed. UFMG, 2001, str. 92-93, eksperiment "Nevidljiva Kristali", obaviti eksperiment nakon čitanja i razgovora s kolegom bilješke, dobiveni rezultat, odnose - s razmatranja donosi tekst "Što se događa" . Elektronički strukture pružiti što više informacija, geometrija molekule, energiju, nekretnine, odnosi na vrste kemijskih veza. Prema tome, stabilnost molekule ovisi o njegovoj energiji, što rezultira iz ravnoteže između privlačnih sila između elektrona i jezgrama i odbojnosti između jezgre i elektrona. Nakon tih razgovora možete reći da zna kako dati "spustiti atoma." Zatim odgovorite: što su vezovi i sidra potrebni za atoma ili molekule do nas sigurno na kraju spustiti, odnosno stabilizirati? materije i njezine prirode
