Â© Ted French. Definition: A function is a preset formula in Excel and Google Spreadsheets. Like formulas, functions begin with the equal sign (=) followed by the function's name and its arguments. The function name tells Excel what calculation to perform. The arguments are contained inside round brackets.
Best Answer: Look for molecular symmetries. Symmetrical molecules such as methane, carbon dioxide, carbon disulfide, and borane (BH3) are nonpolar. Asymmetric molecules such as water, ammonia, and acetone are polar.
We have discussed how bonds can be both polar and nonpolar. These bonds also make the entire molecule polar or nonpolar. Again, it is the polarity that accounts for many of the properties that we see in molecules-most especially, melting and boiling points, as well as solubility.e can think of ionic bonds as being the most polar a bond can be. There is nothing more polar than the ends being different by a whole, complete electrical charge. If a molecule is made of polar bonds, it may be polar or nonpolar.
