Boric acid is its extracted, processed and refined form, found in a variety of chemical products. Determine whether each of the following compounds is likely to exist as a molecule, or as an ionic compound. Hydrogen bonding is a term describing an attractive interaction between a hydrogen atom from a molecule or a molecular fragment XH in which X is more electronegative than H, and an atom or a group of atoms in the same or a different molecule, in which there is evidence of bond formation. (As a comparison, the molecular compound water melts at 0 C and boils at 100 C.) What is the difference between covalent bonds and ionic bonds? Separately they are K+ and O2-. What are molecular compounds and what is the resulting bond called? An alloy is a mixture of metals that has bulk metallic properties different from those of its constituent elements. 3.113.146 g/cm3, monoclinic.

Exercise 2: Naming Chemical Compounds Data Table 2. a group of covalently bonded atoms with an overall charge. A single crystal of C60 falls into which class of crystalline solids? KEY TERMS: Chapter 6 Ionic and Molecular Compounds What is the sum of the ionic charges in an ionic compound? Self-healing rubber is an example of a molecular solid with the potential for significant commercial applications. First off, the charge of the ion is not included. b. from Mg to Ba b.

Na2O What are dispersion forces and how do they occur? If dipole do not cancel each other out. b. oxygen and bromine As a result, they tend to be rather soft and have low melting points, which depend on their molecular structure. Metals tend to form cations and hence most ionic compounds contain a metal. There will never be an earthquake in the "lowest hazard" location in the future. between molecules are much smaller and molecular compounds are gases, liquids or solids with low melting points. b.
