How to Make a Model of Titanium

Glue 22 black buttons and 26 red buttons onto the surface of a plastic ball. Space them evenly across the surface to represent the 22 protons and 26 neutrons in the nucleus of a titanium atom.

Bend a length of model maker's wire around a cylindrical object, roughly 12 to 18 inches in diameter, to form a wire ring. Slide 22 white beads onto the wire, then link together the ends of the wire with strong tape.

Space the white beads evenly around the wire ring and glue them into position to represent the 22 electrons in orbit around the nucleus.

Glue one end of a piece of fishing line to the nucleus ball, then allow the glue to dry. Tie the fishing line to the wire ring, so the nucleus hangs in the center. A drop of glue on the knot seals it and prevents it from coming undone. Measure an additional foot or two of fishing line, then cut it.

Tie a loop in the end of the line and hang the model titanium atom from the loop.
