There are two ways to recognize ionic compounds: An ionic compound can be identified by its chemical formula: metal + nonmetal or polyatomic ions. 1. Compounds between metal and nonmetal elements are usually ionic. 2. If you recognize the formula of a polyatomic ion in a compound, the comp...
This chapter focuses on the chemical bonding in compounds. When two different elements combine together to form a chemical compound the bonding among the elements can be classified into four main types, namely, ionic bonding, covalent bonding, dative covalent bonding, and intermolecular bonding. ...
Ionic Bonding and Ionic Compounds I can classify a bond as ionic and describe the characteristics including bond length, bond energy, and lattice structure. 5. Formation of Ionic Compound s Compounds composed of cations and anions are called ionic compounds. Although they are composed of ions, io...

Ionic compounds are the chemical compounds formed from ionic bonding between cations (positive ions) and anions (negative ions). Unlike in molecules, the attractions that keep ions in compounds together are weak electrostatic forces. A popular example of an ionic compound is sodium chloride. Ever ...

Polarization is effectively a directional, electron sharing effect, hence it introduces a small amount of covalency in ionic compounds. The proportion of ionic/covalent behavior in a bond can be very roughly assessed using the Pauling scale of electronegativity. Linus Pauling estimated that an ...
Solid state 11B (and in one case 10B) NMR spectra of four cyclic boron-chalcogen compounds have been measured at various frequencies and analysed in terms of nuclear quadrupole and chemical shift interactions. Application of the Townes-Dailey theory to the quadrupole results, corrected for ionic co...
