I think it's the valence shell
Outer energy level electrons, or valence electron.
The area around the atom where electrons are most likely to be found spinning is called the electron cloud or electron orbital. This region represents the probability of finding an electron at a particular location around the nucleus.
The 3 dimensional region around a nucleus where an electron is likely to be found is called an electron cloud or electron orbital. This region represents the probability of finding an electron at a particular location within the atom.
Electrons are the subatomic particles that determine the reactivity of an element. The number of electrons in the outermost shell of an atom, known as valence electrons, determines how likely an atom is to form chemical bonds with other atoms.
It is called the electron cloud, the volume in which electrons are most likely to be found. This area is given by Schrodinger's wave equation, which defines psi, the wave function, which squared (psi2) is the probability density. Thus, high probability density equates high electron density. so get over it!
These are called valence electrons.
an ion
The outermost electrons are called VALENCE electrons.
The electrons in the outermost orbital used in chemical bonding are called valence electrons. They are involved in forming bonds with other atoms to complete the octet rule and achieve stability.
Electrons farthest from nucleus are valence electrons. They are present in outermost orbit.
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.
All of 11 electrons in sodium are in different electron orbitals: 2 electrons are in 1s orbital, 2 in 2s, 6 in 2p and 1 in the 3s orbital. (This last one is the so-called valence electron)
octet rule. This rule states that atoms tend to gain, lose, or share electrons in order to achieve a stable electron configuration with eight electrons in their outermost energy level, similar to the noble gases.
they are called electron shells or sometime orbits. there are 32 electron shells. this is also called the electric cloud in the modern atomic model.
An electron in the outermost energy level of an atom is called a valence electron.(We refer here to the outermost occupied levels of an atom. There are, of course, many other higher energy levels normally available that are not occupied.)These electrons determine the chemical reactivity of the atom.the valence electrons
Electrons in the outermost shell are called valence electrons.
materials that usually have an extra or unpaired electron in their outermost orbital of its atom conduct electricity
