(3 points) Ionic compounds usually have higher melting points. This is because the atoms of covalent compounds are bound strongly to each other in stable molecules‚ but those molecules are in general not very strongly attracted to other molecules in the compound. On the other hand‚ the atoms in ionic compounds show strong attractions to other ions in

Compare and contrast the structure and bonding in Ionic‚ Covalent and Metallic species. Relate the structure and bonding to the properties of the species. Ionic bonding is usually formed between a metal and a non-metal‚ Covalent between two non-metals and Metallic between two metals. Ionic Bonding; Ionic bonds tend to form between metals whose atoms need to “loose” electrons to gain the nearest noble gas configuration and non-metals that need to gain electrons. These electrons are transferred

In test one‚ the concrete strength for both‚ the ABAQUS model‚ Experimental model and design failure were at 26 MPa. There was no need to make any adjustments to the existing data in order to get realistic comparisons with data. Both concrete models consisted of a concrete strength of 26 MPa (ABAQUS and experimental data). The data shows that the design failure (As predicted by The Green Book) is designed very conservative‚ because the
