Monatomic or monoatomic elements are elements that are stable as single atoms. Mon-or Mono-means one. In order for an element to be stable by itself, it needs to have a stable octet of valence electrons.The noble gases exist as monatomic elements:1  helium. 2  neon. 3  argon. 4  krypton. 5  xenon.6  radon.onatomic or monoatomic elements are elements that are stable as single atoms.

Axial load (or thrust load) is a force applied parallel to the longitudinal axis, whereas, a radial load is a force applied transverse to this longitudinal axis. + 29 others found this useful. Amit Kr. Edit.
Efficiency. The fact that the forces on each truss member are axial is the key to a trussâs efficiency. In an axially-loaded member, the force is carried equally by every part of the memberâno part is wasted. Contrast this to a beam. When you load a beam at the center, the stresses are much higher there than anywhere else.
