The valance shell is important in chemical reactions, as it is the valance electrons which are gained/lost during reactions. An atoms valance electron configuration is what largely determines its chemical reactivity.

What energy shell determines the chemical properties of an atom?

The valence shell containing the valence electrons used in chemical reactions.


What are valence shells?

Electrons in the outermost orbitals of an atom. They determine the chemical reactivity of an atom and are the primary electrons that participate in chemical reactions.


Why do things create a chemical reaction?

Chemical reactions occur so that atoms can gain a noble gas valence shell configuration in their valence shell and become stable and have lower energy.


Where are the electrons involved in chemical reactions?

The valence electrons (electrons present in the outer most shell) are involved in a chemical reaction.


What are found in an atoms outer shell?

Electrons are found in an atom's outer shell. The outer shell, also known as the valence shell, is where the electrons involved in chemical reactions and bonding are located. The number of electrons in the outer shell determines the atom's chemical properties.


What are valence shell electrons?

Electrons in the outermost orbitals of an atom. They determine the chemical reactivity of an atom and are the primary electrons that participate in chemical reactions.


How many electrons are found in the valence shell of a sodium atom?

the valence shell is the outermost shell of an atom that has free electrons for taking part in chemical reactions... the valence shell of sodium has one free electron


What word describes the outermost shell of the electrons?

The VALENCE Shell. In any chemical reaction it is the electrons in the Valence Shell that do the reacting. Any inner shells of electrons do NOT take part in a chemical reaction.


The electrons that occupy the outermost filled shell are called?

Outer energy level electrons, or valence electron.


Valence electrons for sulfur?

Sulfur has 6 valence electrons, which are located in the 3rd shell or outermost energy level of the atom. These electrons are involved in chemical bonding and determine the reactivity of sulfur in chemical reactions.


What are Valence elcetrons?

Valence electrons are the electrons in the outermost energy level of an atom. They are involved in chemical bonding and determine the reactivity of an element. The number of valence electrons influences the element's properties and behavior in chemical reactions.


What part of the atom does chemical reactons occur?

Chemical reactions occur in the outermost shell of an atom, known as the valence shell. This is where electrons are involved in bonding with other atoms to form molecules. The interactions between these valence electrons determine the chemical properties and reactivity of an atom.
