Does higher electronegativity mean stronger bond?

Does higher electronegativity mean stronger bond? Generally, yes. A bigger difference in electronegativity indicates that the bond is more ionic. Since ionic bonds are known to have strong bonding characteristics, it makes sense that the more ionic a bond is, the stronger the bond. How does electronegativity affect melting point? As you must be knowing, […]

Can science explain bicycles?

Can science explain bicycles? Engineer Jim Papadopoulos, the subject of Scientific American’s feature, demonstrated that a bike with significant negative trail can be ridden, as long as it has a weight jutting out front. That weight could, in theory, come from cargo on a front rack. How do I make my bike pedal easier? Eight […]

What is the difference between DNA and proteins?

What is the difference between DNA and proteins? DNA contains the genetic information of all living organisms. Proteins are large molecules made up by 20 small molecules called amino acids. All living organisms have the same 20 amino acids, but they are arranged in different ways and this determines the different function for each protein. […]
