Polar vs. Nonpolar - STLCC.edu

Polar and Nonpolar Covalent Bonds. Nonpolar Covalent Bond. A bond between 2 nonmetal atoms that have the same electronegativity and therefore have equal sharing of the bonding electron pair. Example: In H-H each H atom has an electronegativity value of 2.1, therefore the covalent bond between them is considered nonpolar.

The Photoelectric Effect | Introduction to Chemistry

The photoelectric effect has been demonstrated using light with energies from a few electronvolts (eV) to over 1 MeV in high atomic nuer elements. Study of the photoelectric effect led to an improved understanding of quantum mechanics as well as an appreciation of the wave-particle duality of light.

Is Silicon a Metal or Nonmetal?

2020/3/25· Silicon is a metalloid, which means it is a type of metal but has some nonmetal qualities depending on what element it is reacting with. An example of this would be the fact that silicon is not a good conductor of electricity. Silicon is part of group 14 on the periodic table, which is considered a metall…
