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, […]
Which line of defense is most important?
Which line of defense is most important? The third line of defense is most important because it involves the cells and proteins of adaptive immunity, responding directly to specific antigens. All three lines of defense depend on each other to function properly and no single line is more important than the other. What is the […]

This happens because each color has a particular wavelength and each wavelength bends at a different angle. What happens if light passes through 2 […]
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 […]
