How can we understand the reflection of light by a metal surface?

A piece of metal has electrons free to move through the entire solid. This is what makes a metal a metal: it conducts both electricity and heat easily, both are actually carried by currents of these freely moving electrons.  (Well,

What is Blackbody Radiation?

What is meant by the phrase “black body” radiation? The point is that the radiation from a heated body depends to some extent on the body being heated. To see this most easily, let’s back up momentarily and consider how

What is inductive effect?

An inductive effect is simply the shifting of electrons in a sigma  bond in response to the electronegativity of nearby atoms. Metals, such as lithium and magnesium, inductively donate electrons, whereas reactive nonmetals, such as oxygen and nitrogen, inductively withdraw electrons. Inductive  effects

Why organic compounds show polarity?

Bond polarity is due to differences in electronegativity (EN), the intrinsic ability of an atom to attract the shared electrons in a covalent bond. Electronegativities are based on an arbitrary scale, with fluorine being the most electronegative (EN  4.0) and cesium, the

Why can’t an organic molecule have the formula C2H7?

Why can’t an organic molecule have the formula C2H7 Each of the two carbons has 4 valence electrons. Two electrons are used to form the carbon–carbon bond, and the 6 electrons that remain can form bonds with a maximum of
