Pretty much any element(in your case sodium) contain these properties.
Atoms can be an ion, but not all ions are atoms. The difference between an atom and an ion has to do with net electrical charge. An ion is a particle or collection of particles with a net positive or negative charge. ... A stable atom contains the same number of electrons as protons and no net charge

Answer:
C. a motorcycle changing speed from 20km/h to 35km/h
Explanation:
The choice not showing unbalanced forces acting on the object is a motorcycle changing speed from 20km/h to 35km/h.
This change in velocity shows that the body is accelerating during the time interval.
When a body is accelerating, it is changing it's motion and this implies that some unbalanced forces are acting in the body. Unbalanced body changes the state of motion of a body from rest to acceleration or deceleration as the case may be.
