A valence electron is an electron that is the most likely to be involved in a chemical reaction. They are typically the electrons with the highest value of the principal quantum number, n. Another way to think of valence electrons is that they are the outermost electrons in an atom, so they are the most susceptible to participation in chemical bond formation or ionization.

- In chemistry and physics, a valence electron is an electron associated with an atom that can form a chemical bond and participate in a chemical reactions.
- Carbon has four valence electrons and here a valence of four. Each hydrogen atom has one valence electron and is univalent.
- Yayın zamanı: dünValence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell...
- Valence electrons play a vital role in determining the chemical properties of an element and its ability to form bonds with other elements.
- Detailed explanation-3: -This outermost shell is known as the valence shell, and the electrons found in it are called valence electrons.
- That is, the total number of electrons in the last orbit of an element after electron configuration is called the valence electrons.
- Valence electrons are those electrons that reside in the outermost shell surrounding an atomic nucleus.
- As we proceed downwards in a group, the numbers of valence electrons are same, although the number of shells increases.
- Consequently, the valence electrons are loosely held; therefore, they participate in chemical reactions by being gained, lost, or shared.
- Therefore, a valence electron belonging to a transition element is at a location other than the noble gases core, in contrast to the main group elements.
