PRODUCT DESIGN. Product design is cross-functional, knowledge-intensive work that has become increasingly important in today's fast-paced, globally competitive environment. It is a key strategic activity in many firms because new products contribute significantly to sales revenue.
Covalent bonds form when two atoms have a very small (nearly insignificant) difference in electronegativity. The value of difference in electronegativity between two atoms in a covalent bond is less than 1.7.Covalent bonds often form between similar atoms, nonmetal to nonmetal or metal to metal. Covalent bonding signals a complete sharing of electrons.olar Covalent Bonds. Polar covalent bonds fall between ionic and covalent bonds. They result when two elements bond with a moderate difference in electronegativity moderately to greatly, but they do not surpass 1.7 in electronegativity difference.
In ionic bonds, one atom donates its valence electrons to another atom in the formation of the bond. Covalent bonds form when atoms are able to share valence electrons. However, if the attraction for electrons is greater in one atom than the other, the electrons tend to orbit the stronger atom. As a result, the molecule tends to have a positive end and a negative end and the bond is a polar covalent bond. Water forms polar molecules. Metal atoms join together through metallic bonds.
