what term is used to describe the lowest energy level of a particle?
154034
If an atom, ion, or molecule is at the lowest possible energy level, it and its electrons are said to be in the ground state. If it is at a higher energy level, it is said to be excited, or any electrons that have higher energy than the ground state are excited.

The lowest energy level is the # 1s^2 The 1 s orbital is a spherical orbital in the first electron shell. These two electrons fill the shell or energy space closest to the nucleus. An electron shell is a space around the nucleus that is filled forces any more electrons further out from the nucleus.

The outermost energy level that (in the ground state of the atom) contains electrons is called the "valence shell" of the atom. These valence electrons are responsible for all chemical bonds between atoms. For silicon, the valence shell corresponds to a principle quantum number n of 3.

The orbits of an atom actually represent the energy levels of the electrons in it. The energy level decreases as the shell number increases. ... The orbits are named according to the energy levels or electrons in it. Hence orbits (shells) are also called energy levels.

noun. the lowest temperature theoretically attainable, at which the particles constituting matter would be in the lowest energy states available; the zero of thermodynamic temperature; zero on the International Practical Scale of Temperature: equivalent to –273.15°C or –459.67°F.

The red light has the longest wavelength, lowest energy, and lowest frequency. The shorter the drop from one energy level to another, the less energy, in the form of light/photons is emitted.

In summary, a photon is the tiniest possible particle of light, a quantum of light. A quantum, on the other hand, is the tiniest possible particle of any substance at the subatomic level and includes, for example, electrons and neutrinos. If this answers your question, no need to read any further.

Summary. Electrons are a type of subatomic particle with a negative charge. Protons are a type of subatomic particle with a positive charge. Protons are bound together in an atom's nucleus as a result of the strong nuclear force. Neutrons are a type of subatomic particle with no charge (they're neutral).

absolute zero. The lowest possible temperature, at which all molecules are have the least possible amount of kinetic energy. Absolute zero is equal to 0°K, -459.67°F, or -273.15°C. At temperatures approaching absolute zero, the physical characteristics of some substances change significantly.

To completely describe an electron in an atom, four quantum numbers are needed: energy (n), angular momentum (ℓ), magnetic moment (mℓ), and spin (ms). The first quantum number describes the electron shell, or energy level, of an atom.

The fixed energies an electron can have are called energy levels. Each possible electron orbit in Bohr's model has a fixed energy. The fixed energies an electron can have are called energy levels. energy required to move an electron from one energy level to another energy level.

The lowest energy level (the K shell) can only be occupied by two electrons, the L shell by 8 and the M shell by 18. The K shell electrons are closest to the nucleus. ... Electrons can't have whatever energy values they want, and each value is associated with a specific orbit trajectory.
