A coarse particle has a diameter of 1x10-6m. a nanoparticle has a diameter of 1.6 x 10-9m. Calculate how many times bigger the diameter of the coarse particle is than the diameter of the nanoparticle
There are 3 pairs of electrons that are shared between nitrogen atoms in a nitrogen molecule. Nitrogen atom has a valence electron of 5. To complete it and agree with the octet rule, it should be that three electrons should share with another atom.
