Item No. Name Bond Length Bond Arrangement Color Angle Shape
Bio-1 Carbon Tetrahedral-1 0.77 Black 109° 28'
Bio-2 Nitrogen Tetrahedral-1 0.77 Blue 109° 28'
Bio-3 Oxygen Tetrahedral-1 0.77 Red 109° 28'
Bio-4 Phosphorus Tetrahedral-1 0.77 Yellow 109° 28'


A regular tetrahedral-1 has 4 bonds each extending from the center at bond angle of 109° 28'. from adjacent bonds.
Three of them are 'Horn'-shaped and works as male ( + ) for connection. .
Remaining one work as female ( - ) using the hole.
Connecting one part to another with connectors will form a chain hydrocarbon.
Bond length is same in Carbon Tetrahedral-1(black), Nitrogen Tetrahedral-1 (blue), Oxygen Tetrahedral-1(red). Accuracy may be enough (It is different 0.05 mm carbon from oxygen.) for simply viewing shape of molecule, although it depends on the purpose of constructing a structure.
