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.

valence electrons are the electrons in the outermost energy level


What are electrically charged atom or group of atmos with unpaired electrons in their outermost shell?

An electrically charged atom or group of atoms with an unpaired electron in its outermost shell is called a free radical. If the outermost shell of an atom is half-filled with electrons, that atom is most likely to share electrons.


What word means the number of electrons in the outer shell?

Valence electrons


Describes an atom that has a full outermost energy level?

An atom with a full outermost energy level is considered stable. This means that the atom is less likely to form chemical bonds with other atoms to achieve a full outer shell of electrons. The noble gases, such as helium and neon, are examples of elements with full outer energy levels.


What word refers to the largest number of electrons?

The term you are looking for is "valence electrons." Valence electrons are the electrons in the outermost energy level of an atom, and they play a crucial role in determining the chemical properties of an element.


How many electrons are in oxygen's outer level?

The word "valance" is used to describe electrons in the outer-most energy level of an atom. Oxygen has six valance electrons.


What is a stable octet mean?

a stable octet is also known as a full outer shell. it occurs when electrons are added or removed from an atom so the outtermost shell contains its maximum amount, funnily enough Helium is included because is has a full outer shell as opposed to the direct meaning of a full octet. the term full octet refers to the outtermost shell being complete, however a direct definition means the outtermost shell containing EIGHT electrons, which simply isn't possible for something like Helium or Hydrogen. in which case, the full octet of either Helium or Hydrogen is two electrons- this would give Helium no charge at all, but would give Hydrogen a -1 charge, in a diatomic molecule two Hydrogen atoms would share their electrons between them: H=H <--Hydrogen / Helium --> He (would not donate or adopt electrons) more interstingly is the FORMS of Hydrogen. there are three: Hydrogen, deuterium and tritium.


The nucleus and all electrons in an atom except the valence electrons?

The nucleus of an atom contains protons and neutrons. Valence electrons are the outermost electrons in an atom that participate in chemical bonding. The electrons in the inner energy levels, excluding the valence electrons, are referred to as core electrons.

According to the octet rule what is the ideal number of electrons in the valence shell?

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell with 8 electrons, resembling the electron configuration of noble gases. For some elements such as hydrogen and helium, a full valence shell may consist of just 2 electrons.


What is a compound word for shell?

How can you use the word stable to explain why the alkali metals tend to lose valence electrons?

The alkali metals tend to lose valence electrons because they have one electron in their outermost energy level, which makes them unstable. By losing this electron and achieving a full outer shell, they become more stable like the noble gases. This stability is the driving force behind their tendency to lose valence electrons.
