Niels Bohr contributed the quantum theory of atomic structure which basically states that an atom emits electromagnetic radiation only when an electron changes from one energy level to another, thereby changing our understanding of atomic "shells" to think of them more as energy levels that are to some extent inter-navigable by the electrons. He based his theories on the extensive work of Max Planck and Ernest Rutherford and contributed greatly to today's research of quantum physics which is our future.

Glow appears in a discharge tube due to electrons colliding with gas atoms, exciting them to higher energy levels. When the excited atoms return to their ground state, they release photons of light, creating the glow.
Photons have no charge, no rest mass and travel at the speed of light throuh a vacuum. Electrons have a charge of -1, have rest mass and are part of atoms.

Albert Einstein called the quanta of light energy "photons."

EM waves are not made out of atoms -- they come in "chunks" called photons. But photons and atoms are completely different things. The statement, "light is composed of many atoms" is almost completely wrong.
Photons are particles of light that carry energy. When light is absorbed by a material, photons transfer their energy to the material's atoms, causing them to become excited. This excitation can lead to the emission of light when the atoms return to their original state, releasing photons in the process.
Einstein's work on the photoelectric effect showed that light behaves as particles (photons), challenging the established wave theory. He also developed the theory of special relativity, which showed that matter and energy are interchangeable (E=mc^2), revolutionizing our understanding of the relationship between mass and energy at the atomic level.
Einstein, and he used the theory to describe the photoelectric effect.
Bose-Einstein statistics describe the behavior of indistinguishable particles with integer spin, such as photons and helium-4 atoms, at low temperatures. This statistical mechanics approach helps understand phenomena like the formation of Bose-Einstein condensates and the behavior of superfluids. Applications include laser technology, superconductivity, and quantum computing.

Light is composed of very small packages of electromagnetic energy called photons. We are able to see objects because light photons from the sun (or other light source) reflect off of the atoms within the object and some of these reflected photons reach the light sensors in our eyes and we can see the objects. It takes many millions of photons entering our eyes each second for us to view the world. When photons of light hit the atoms within an object three things can happen. First, the photons can bounce back from the atoms in the object; we call this reflection. Second, the photons can pass through an object such as glass and we call them transparent. Three, the photons can be stopped by the atoms within the object and the photon energy is converted to heat; we call this absorption.
Yes, fire flames produce photons as a result of the high temperatures causing atoms and molecules in the flames to emit light energy. These photons are the visible light that we see when a fire burns.
