What element has the highest occupied energy level?
What element has the highest occupied energy level?
As you know, an element’s valence electrons are simply the electrons located on the outermost energy level, i.e. on the highest occupied energy level. Therefore, you can say that an element located in group 5A has 5 electrons on its highest occupied energy level.
What is the highest occupied sublevel in that atom?
Chemistry – Chap 6 Vocabulary
| A | B |
|---|---|
| inner transition metals | An element in the lanthanide or actinice series, the highest occupied s sublevel and nearby f sublevel of its atoms generally contain electrons; also called inner transition elements |
| ion | A charged atom or groups of atoms – may be either positive or negative |
Does all matter decay?
Although most particles disintegrate [the technical term is “decay”] into other particles, a few types of particles do not. Protons, for instance, are so long-lived that at most a minuscule fraction of them have decayed since the Big Bang, so for all practical purposes they are probably stable.
Can energy decay?
“In quantum mechanics, and in particular in quantum field theory, Heisenberg uncertainty principle allows energy to briefly decay into particles and antiparticles which then annihilate back to energy without violating physical conservation laws.”…
Is energy released in alpha decay?
Alpha decay is fundamentally a quantum tunneling process. In some radioactive substances, when beta decay occurs along with alpha decay, atomic helium is formed. Most alpha particles are emitted with approximately 5 MeV of kinetic energy.
Is energy released in beta decay?
Energy release In beta decay, Q is therefore also the sum of the kinetic energies of the emitted beta particle, neutrino, and recoiling nucleus. Beta particles can therefore be emitted with any kinetic energy ranging from 0 to Q. A typical Q is around 1 MeV, but can range from a few keV to a few tens of MeV.
What type of energy is radioactive decay?
Radioactive decay is the process in which an unstable atomic nucleus loses energy by emitting ionizing particles and radiation. This decay, or loss of energy, results in an atom of one type, called the parent nuclide transforming to an atom of a different type, called the daughter nuclide.
