Periodic characteristics
WebA periodic function is a function that repeats its values at regular intervals. For example, the trigonometric functions, which repeat at intervals of radians, are periodic functions. Periodic functions are used throughout science to describe oscillations, waves, and other phenomena that exhibit periodicity. WebIt holds the lowest boiling and melting points amongst all other elements. Nuclear fusion of hydrogen in stars generates a significant amount of helium. Isotopes Helium has two known stable isotopes – 3 He and 4 He. The abundance of helium-3 and helium-4 corresponds to 0.0002% and 99.9998% respectively.
