1. distinguish relationships in addition to properties of elements, list at least two other things or events that are periodic.

Answer

Brief Explanations:

Periodic events repeat at regular intervals. The rotation of the Earth on its axis (causing day - night cycle) and the revolution of the Earth around the Sun (causing seasons) are periodic. Also, the swing of a pendulum in a clock under ideal conditions is periodic as it repeats its motion at regular time intervals.

Answer:

  1. The rotation of the Earth on its axis (causing day - night cycle).
  2. The revolution of the Earth around the Sun (causing seasons).
