Based on the location of nitrogen (n)on the periodic table how many additional electrons does a nitrogen atom need in its valence shell to satisfy the octect rule when it forms bonds

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
