Mercury or just look at a periodic table or look on other websites like - www.cas.org
Lithium, just look at the periodic table.
Look for predictable changes and patters.

continuous,regular and rythmic disturbances in a medium result from periodic vibrations of a source which cause periodic waves in that medium.
Vibration refers to mechanical oscillations about an equilibrium point. The oscillations may be periodic such as the motion of a pendulum or random such as the movement of a tire on a gravel road.sorce-wikipedia

Many oscillations are simple harmonic motions and such motion can be represented by a sine (or equivalently, cosine) curve.

Damped (or free) oscillation occurs when an object is set to vibrate at its natural frequency while forced oscillation involves the application of a force to keep an object in constant or repetitive motion.
Vibration works when a rigid or elastic body or medium oscillates from a position or state of equilibrium. The oscillations can be either periodic or random.
