Web(i) Showing outer-shell electrons only, draw a ‘dot-and-cross’ diagram of an ammonia molecule. (ii) Draw a diagram to show the three-dimensional shape of an ammonia molecule. (iii) Draw a diagram to show the shape of a hydrazine molecule. Show clearly which atom is joined to which and show clearly the value of one bond angle. [4] WebDec 30, 2024 · And hydrogen only needs one electron to complete its valence shell. ⇒ Valence electron in carbon = 4. ⇒ Hydrogen valence electron = 1. ∴ Total valence electrons available for C2H4 lewis structure = 4*2 + 1*4 = 12 valence electrons [∴ C2H4 has two carbon and 4 hydrogen atom] 2. Find the least electronegative atom and placed it at center. Web1 day ago · In the case of N2H2, a single molecule has two atoms of nitrogen and two atoms of hydrogen.
