- 2. It is a chemical rule of thumb, which reflects the theory that keygroup elements tend to bond in such a way as each atom's valence shell contains eight electrons.
- 5. the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire
- 8. an atom with a net electric charge
- 10. It's an ion with positive charge
- 11. It's an ion with negative charge
- 12. The energy content of an electron is determined by a shell or orbital on which the electron resides relative to the atom's nucleus.
- 14. is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus during the process of beta decay.
- 15. Define the location of electrons near the atom nucleus.
- 17. A particle representing a quantum of light, or some kind of cosmic radiation. The photon has an energy that is proportional to the radiation frequency, but it does not have any rest mass.
- 18. penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei.
- 19. The atomic or other particle's lowest energy state.
- 21. It represents the reactants and products of radioactive decay, nuclear fission or fusion.
- 22. An energy level that has been defined by quantum theory. Energy related to electrons is referred to as a sub level in chemistry. The energies associated with a nucleus can also be regarded as sublevels in physics.
Down
- 1. the number of waves that pass a fixed point in unit time
- 3. The valence shell electrons in a molecule are represented in a very simplified way.
- 4. the electrons located at the outermost shell of an atom.
- 6. They are composed of two protons and two neutrons bound together into an entity identical to the helium-4 nucleus.
- 7. It is formed by direct observation of the excited gas through a spectroscope
- 9. It is an energy form that behaves as both magnetic and electric waves, traveling in a series of particles known as photons.
- 13. is energy from a source, which travels in space at light speed.
- 16. We're providing secure, end to end solutions for the management and preservation of data and the easy extraction of information from it.
- 20. The spontaneous fission of atomic nuclei produces the release of ionising radiation or particles.
