The energy is higher.
The energy is higher.
The energy of the valence electrons is greater than the energy of the core electrons.
Core electrons have lower energy compared to valence electrons. Core electrons are located closer to the nucleus, experience a higher effective nuclear charge, and are more shielded by inner electron shells, leading to lower energy levels. Valence electrons are found in the outermost energy level and have higher energy due to their increased distance from the nucleus and lower shielding effect.
Valence electrons.
valence electrons are bound to atoms and are used to bind atoms into molecules. free electron are free, either they are in the conduction band "electron gas" of a metal or they are in a vacuum (perhaps in a vacuum tube).
The energy is higher.
The energy is higher.
The outermost electrons are called VALENCE electrons.
The period tells you the valence ELECTRON SHELL (energy level). The group tells you the number of valence electrons.
They are called valence electrons, and they are responsible for an atom's chemical properties. During a chemical reaction, the valence electrons are the only part of an atom that participates.
To determine the number of valence electrons in an atom using its electron configuration, look at the highest energy level (n) in the electron configuration. The number of electrons in this energy level is the number of valence electrons.
To determine the number of valence electrons from an electron configuration, look at the highest energy level (n value) of the electrons in the configuration. The number of electrons in this highest energy level is the number of valence electrons.
