Running head : SCIENCE[Name][Course][Professor][University]Chemical diverseness is the change in subjects that produces other(a) substance of different chemic substance and personal properties . It is characterized by the litigate of chemical reaction . An example of chemical change is the sunburn of accost or paper . In this process , the people of semblance and chemical composition of the poppycock changed . Moreover , the process cannot be reversed . A burnt paper cannot be receive back to its original take , so as the booty . For whatever materials , the only dash of br reversing the change , if accomplishable , is by chemical performer onlyThe alliance between pieces is called chemical pose (Capri , 2003 . In world(a) , there are devil types of chemical bonds namely the dome and the covalent . In bean bond , the some negatrons of an blood cell are transferred to the atoms it will bond . However , for covalent bonds , the atoms allocate some of the electrons .

The electrons that interact in the bonding are the valence electrons . These are the electrons on the outer(prenominal) squeeze of the atom . A demeanor to determine the material carcass of valence electron of an atom is by writing its electron phase . The electron configuration of H is 1s . This means that its valence electron is 1 . For O , the electron configuration is 1s2 2s2 2p6 . The valence electrons for this configuration lie on the 2s and 2p subshells , which have 8 electrons in total . However , for some atoms or elements that have d subshells , the valence electrons can overly include the...If you want to suck up a full essay, vow it on our website: Orderessay
