What is the wavelength (in meters) of an electron travelling at 8.10 x 106 m s-l? Remember that 1 Joule = 1 kg m’s-?

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.

it is stable as it is in group 0 which have full outer shells of electrons
