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.
Best Answer: Carbon usually makes four covalent bonds, due to its four free valence electrons. These may be single, double or triple bonds, depending on the compound. Nitrogen makes three, since it has five valence electrons and needs three to fulfill the octet rule. Oxygen needs two to fulfill its octet, so it can make two bonds. Hydrogen has one electron in its 1s orbital, and does not follow the octet rule. It can only make one covalent bond, completing the 1s inner shell.
