... The problem with classical physics of the time was that an electron orbiting a nucleus would lose energy & eventually collapse into the nucleus. In Bohr’s model, an electron can travel around a nucleus without radiating energy. Furthermore, an electron in a given orbit has a certain definite amount ...

Polar and Nonpolar Covalent Compounds
... Recall that polarity refers to an unequal sharing of electrons resulting from differences in electronegativity. There is a distinction between polar bonds and polar molecules. A polar covalent bond occurs when bonding electrons are more attracted to an atom with a higher electronegativity. The polar ...
