In the ammonia (NH_3) molecule, the three hydrogen (H) atoms form an equilateral triangle; the center of the triangle is 9.40*10^-11 m from each hydrogen atom. The nitrogen (N) atom is the apex of a pyramid, with the three hydrogen atoms forming a base. The nitrogen-to-hydrogen atomic mass ratio is 13.9, and the nitrogen-to-hydrogen distance is 10.14*10^-11 m. Locate the center of mass of the molecule relative to the nitrogen atom, and explain how you got your answer.

Protons have a +a million charge NEUTRONS have a impartial charge Electrons have a -a million charge Protons and Neutrons each and every have a mass of about a million amu (Neutrons weigh slightly extra) Electrons have about a million/1836 the mass of a proton Neutrons and Protons are positioned in the middle of an atom, and the electrons are orbiting around the middle. In percentage, the electrons are way a concepts faraway from the middle, notwithstanding it is so small common this is in difficulty-free words assumed to orbit arond it. Atoms are really empty area.

Well, there are three H atoms so the mass ratio of nitrogen to hydrogen is13.9:3 = 4.63. So you start at the H end of one of the N-H bonds and go towards the N atom 4.63/(1+4.63) of the way.Draw an equilateral triangle linking your location to the corresponding points on the other two bonds. The centre of mass is at the centroid of your triangle, in the empty space between the three bonds,
