Chemistry You've managed to identify one of the anchors and / or one of the moorings of the atoms so that they are more stable? An atom joins with another to form a new compound is a new organization between the nuclei of its atoms and their electrons have less energy than the total energy of the separate atoms. When the lowest energy is obtained by transfer of one or more electrons from one atom to another, the compound is maintained by the attraction between the ions and this attraction is called electrostatic force or ionic bond. If the compound can lower energy sharing electrons, ie the electron can be used by two atoms while forming pairs of electrons, atoms will unite through weaker forces, covalent bonds forming molecular compounds. The new bonds formed have less power than the previous organization, as changes in the position of the valence electrons (electrons in the last layer) of atoms. Knowing the family and the time that the atom is located in the periodic table of chemical elements is possible to predict the type and amount of bonds that an atom can form. This makes it possible to provide new compounds of the formulas and explain some of its properties such as the electrical conductivity. Let us analyze the results of the electrical conductivity of the substances you tested? Note that the steel wool, the one used to clean the pots, is solid at room temperature and conducts electricity. Furthermore, common salt is also a solid, electric current does not conduct, but in aqueous solution has high electric conductivity. Other solid substances such as sugar and plastic do not conduct electric current. Furthermore, the passage of electric current through the dissolved salt causes changes in the structure of matter, this is a chemical reaction of a substance, and occurs only in the metal heating. Imagine what it takes these substances have different behavior? Are the anchors or moorings?

Kemija Ste uspjeli identificirati jedan od sidra i / ili jedan od vezova atoma, tako da su stabilniji? Atom spaja s drugom da se formira novi spoj je nova organizacija između čvorova svojih atoma i njihovi elektroni imaju manje energije od ukupne energije od odvojenih atoma. Kada niskoenergetske dobiva se prijenos jednog ili više elektrona iz jednog atoma u drugi, spoj se održava privlačnosti između iona, a to privlačnost zove elektrostatski sila ili ionske veze. Ako spoj može sniziti elektrona energije sharing, tj. elektrona mogu se koristiti dva atoma, dok formiranju para elektrona, atoma će se ujediniti kroz slabijim snagama, kovalentno tvore molekularne spojeve. Nove obveznice formirane imati manje energije od prethodne organizacije, kao promjene u položaju valentni elektroni (elektroni u posljednjem sloju) atoma. Poznavajući obitelj i vrijeme da se atom nalazi u periodni sustav kemijskih elemenata, moguće je predvidjeti vrstu i iznos obveznica koje atom može formirati. To ga čini moguće osigurati nove spojeve formule i objasniti neke od njegovih svojstava, kao što su električne provodljivosti. Neka nam analizirati rezultate električne provodljivosti tvari li testirani? Imajte na umu da čelične vune, jedan koristi za čišćenje i lonce, je kruto na sobnoj temperaturi, a provodi struju. Nadalje, zajednički sol je također solidan, električna struja ne provodi, ali u vodenoj otopini ima visoku električnu vodljivost. Ostale krute tvari poput šećera i umjetnih materijala ne provode električnu struju. Nadalje, prolaz električne struje kroz otopljene soli uzrokuje promjene u strukturi tvari, to je kemijska reakcija tvari, a pojavljuje samo u metalne grijanja. Zamislite što se ove tvari imaju drugačije ponašanje? Jesu li sidra ili privezišta?
