Each colored ball in your kit corresponds to different atom or different group of atoms. Suppose you want to construct a triple bond. The Oxygen is tetrahedral electron geometry and bent molecular geometry. All the atoms have a complete octet in dibromomethane. (5 single bond 2 electrons + 12 electrons represented as dots) = 22 valence electrons are used in the above structure. Since both carbon central atom is bonded with three atoms (one hydrogen, one chlorine, and one another carbon) and it has no lone pair which means, it is an AX 3 type molecule which implies its geometry will be trigonal planar. The formal charge is negative when the electrons on the atom in the compound are more than in an isolated atom and positive when the electrons on the atom in the compound are less than in an isolated atom.

How will you know which color to use for specific atoms? The four outer atoms are evenly arranged in 3D around the central atom as if at the corners of a regular tetrahedron. A negative formal charge is more stable on an electronegative atom than on an electropositive atom and vice-versa. In general, a molecule will be polar if it contains polar bonds that are distributed in a non-symmetrical arrangement around the central atom.
