Covalent bonding is a common type of bonding, in which two or more atoms share up to three valence electrons. In nonpolar covalent bonds, the electronegativity difference between the bonded atoms is small, typically 0 to 0.3. Bonds within most organic compounds are described as covalent.
The Silent Generation refers to people who were born between 1925 and 1945. There are several theories as to where the label 'Silent Generation' originated. The children who grew up during this time worked very hard and kept quiet. It was commonly understood that children should be seen and not heard.
Baby boomers are the demographic cohort following the Silent Generation. There are no precise dates for when this cohort starts or ends. Demographers and researchers typically use birth dates ranging from the early-to-mid 1940s and ending from 1960 to 1964.
