Find the wavelength in nanometers (nm) of a blue light with a frequency of 6.24 x1014 hertz.

gravity causes stares to cluster i think so

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

increased stability in the completion of fluorine's outer shell.

a electronegativity decreases beacuse the size of nucleus is bigger.
