Why radium shine in night its ans?

Answer 1

Radium is a radioactive element which emits an ionizing radiation. By definition, ionizing radiation ionizes nearby atoms (strips one or more electrons from them). This leaves the atom (Radium or others) with a positive charge (an attractor of electrons). As a stray electron finds this newly created ion and reenters the atom's orbitals, it releases photons whose energies are related to the orbitals. These released photons are the "Shining" observed.

Answer 2

As it is radioactive..........electrons in the higher levels are unstable....so they fall to lower energy levels giving out energy in form of EM waves....since few of the wavelength of it is as that of visible li8 so thats what creates the glow.... :)I hope it helps...

Answer 3

Radium emits light because of its radioactive properties. When radium atoms decay, they release energy in the form of radiation that can cause nearby materials to fluoresce or emit light. This property makes radium useful in glow-in-the-dark products like clock dials or watch hands. However, it's important to handle radium with caution due to its health risks.

Answer 4

Because radium is a radioactive metal emitting alpha, beta and gamma radiations.
