Explain Electronic theory of colors

Answer 1

Electronic Color Theory"Electronic color theory" is a recent misnomer for additive color theory. Additive color theory predicts what colors will be perceived when different colors of light are mixed. It is differentiated from subtractive color theory, which predicts what colors will be perceived when different colors of pigment are mixed.

Additive color theory has been around for about 150 years, since it was first proposed and demonstrated by James Clerk Maxwell. It has recently been called "electronic color theory" in some undergraduate computer science courses, since it is most commonly applied to the light emitted by a CRT, LCD or plasma television and computer displays.

It has no relevance to Rutherford's model of the atom.
Nucleus surrounded by moving electronsErnest Rutherford performed a famous experiment which demonstrated that atoms had a small positively charged central nucleus surrounded by negatively charged electrons. Based on this experiment, he proposed a model of the atom in which electrons moved in the space around the central nucleus.

Rutherford's experiments didn't really contribute to the theory of electron orbitals really. He really established that the atom is mostly empty space, but what is solid, is very solid (in other the words, the nucleus is very small but most of the mass of the atom is in the nucleus). However, he discovered nothing where electrons are found atoms or the shapes of orbitals, or that orbitals even existed. That was really the work of Niels Bohr and those that followed him.
