Emission spectrum is produced by nebulae consisting of atoms that release photons when electrons jump from high-energy states to lower-energy states.
Auroras are produced by interactions among thermospheric gases and free electrons
Auroras are produced by interactions among thermospheric gases and free electrons
From higher to lower energy levels
Balmer lines are produced by colliding hydrogen atoms with electrons excited to 2nd energy level. Cool stars don't have enough collision to excite the electrons, hot stars have too much collision and excite the electrons beyond 2nd energy level.
The Sun's energy is produced in the Sun's core.
Free electrons are produced in ß- decay, the first electrons were produced in the big bang
When atoms lose electrons cations are produced.
Free electrons are produced at the metallic electrode that has atoms, that give up electrons, and become ions in solution.
transferring electrons, gaining electrons, losing electrons and sharing electrons.
Chemical bonds can be only produced by gaining, losing or sharing electrons. If a compound is formed by losing or gaining electrons, it is called an ionic bond and if by sharing electrons, it is called a covalent bond.
It is electricity (or electrical energy) that we find is used in homes, and it is produced by the movement of electrons.
It is electricity, produced by the movement of electrons, that is a form of energy we use in homes.
It is electricity (or electrical energy) that we find is used in homes, and it is produced by the movement of electrons.
The movement of free electrons is' electricity. So electrons can not produce electricity; but it is produced by magnetism.
