The first compound telescope was made by German astronomer Bernhard Schmidt in 1930. The Schmidt telescope had a primary mirror at the back of the telescope, and a glass corrector plate in the front of the telescope to remove spherical aberration. The telescope was used primarily for photography...
Explain how to determine if a bond is ionic or covalent or metallic. Covalent Bonding Covalent bonding is often explained as "electron sharing" where electrons are attracted to two different elements with the same force. In terms of orbitals, wavefunctions for electrons initially associat...

Today, the Schmidt-Cassegrain design, which was invented in the 1960s, is the most popular type of telescope; it uses a secondary mirror that bounces light through a hole in the primary mirror to an eyepiece. The second type of compound telescope was invented by a Russian astronomer, D. ...
How do we know if a compound such as NF or NH4 is polar or nonpolar? Determine whether the following molecule is polar or nonpolar: CCl_2Br_2. Determine if the molecule is polar or nonpolar. CH_2Cl_2 How can a molecule that contains polar bonds be nonpolar?
Whether or not a molecule is polar depends entirely upon the polarity of the bonds found in a given compound and some parameters of these bonds. But before delving into how to to determine polarity, here is a quick explanation of polarity ...
