The transition of excited electrons from one allowed energy level to another. As the excited electrons lose their excess energy and return to the ground state, they give out a photon with an energy directly proportional to the energy difference between the electron levels. The photons (light particle/wave) appear different colours depending on the energy of the photon given off.

An atomic bomb uses fission-- the splitting of atoms. It is purely a physical change, at first. Any gases produced in the air surrounding the explosion (which occurs before it touches the ground), along with the intense heat produced, causes chemical changes in the air.
Chemistry is the center and serves as the interface for many other sciences. Chemistry is such a broad subject. Please view the related source link at the bottom of the answer box.It is the study of matter and energy at the subatomic, atomic, and molecular levels.Chemistry is the study of the composition, structure, properties, and chemical reactions of matter.
He is the atomic symbol for Helium
John Dalton first pursued research into atomic theory. He was the first person to propose the existence of the atomic structure.
Colors are produced by means of energy. When a chemical burns, related atomic structure of chemicals excites the electrons which results in the emission of visible light and forms into various colors.
This is the atomic nucleus.
You think probable to the role of electrons.

Cleavage is related to the minerals atomic structure because minerals are arranged in crystal lattices . It's the shape of these lattices that determine the mineral's cleavage.
The chemical symbol for neodymium is Nd. It is a rare earth element with atomic number 60 and belongs to the lanthanide series of the periodic table. Its atomic structure consists of 60 protons, 60 electrons, and varying numbers of neutrons depending on the isotope.
Atomic structure, Chemical composition and External form.
It was originally arranged that way and it produced some conflicts (pairs of elements in the wrong columns for their known chemical properties). Arranging by atomic number (initially arbitrary until the structure of the atom was determined) solved these conflicts.

The physical properties of minerals are determined by their chemical composition and atomic structure.
