Brittle compounds

WebCovalent Compounds. Covalent compounds are chemical compounds that are formed by the sharing of electron pairs between elements. Elements will share a pair of electrons in order to gain a complete outer shell and a stable electron configuration. For example, water consists of one oxygen atom covalently bonded to two hydrogen atoms (H 2 O). WebIonic compounds tend to have high melting and boiling points. Ionic compounds are very hard and very brittle. Ionic compounds conduct electricity when they dissolve in water. Other facts; Ionic compounds are usually formed when metal cations bond with nonmetal anions. The only common exception I know to this is when ammonium is the cation ...

12.7: Types of Crystalline Solids- Molecular, Ionic, and Atomic

WebIonic compounds are composed of positive and negative ions held together by ionic bonds. An Ionic bond is a type of bond that forms between a metal and a non-metal. Molecular compounds are compounds made up of nonmetals. A covalent bond is a type of bond that occurs between two nonmetals. WebIntermetallic compounds are ordered alloys of two or more metals, in definite stoichiometry. From Table 15.2, it is clear that transition metals of group IIIA (Sc, Y, La), group IVA (Ti, Zr, Hf), rare-earth metals and actinides form too stable binary hydrides, from the application point of view (these elements will, hereafter, be referred to as A-elements or hydride …
