The key to "happiness" for an atom is a full outer electron shell. (The outer electron shell is called the valence shell.) There are two conditions that cause a shell not to be full. Either it has only an electron or two (or three) in the outer electron shell or it's short an electron or two in that outer shell. The direct answer to the question is that if an element is chemically active, its outer electron shell is incomplete or is not full.

What makes element becomes active?

An element is chemically active till it does not attain an inert gas configuration.


What does being a chemically active element mean?

i am pretty sure that when an atom is chemically active its outer valence shell is not full meaning it is able to form different types of bonds with different elements.


What is the element that has a high ionization energy and tends to be chemically inactive would most likely be?

Helium would be the element that fits this description. It has a high ionization energy, meaning it requires a lot of energy to remove an electron, and tends to be chemically inactive because its outer electron shell is full.


How many elements does the outer electron have?

An electron is not an element.


What element is stable with 2 valence electrons?

Helium is stable with 2 valence electrons. It has a full outer electron shell, making it chemically inert and stable.


What is an electron configuration that belongs unto an element that is not chemically reactive?

An example of an electron configuration for a chemically non-reactive element is that of neon, which is 1s² 2s² 2p⁶. Neon is a noble gas with a full outer electron shell, making it stable and unreactive. Elements with full valence shells, like the noble gases, typically do not engage in chemical reactions because they do not need to gain, lose, or share electrons.


How chemically active are neon?

Neon is chemically inert, meaning it is very unreactive. Its outer electron shell is full, so it is stable and does not readily form chemical bonds with other elements. This property makes neon useful for applications where a non-reactive atmosphere is needed, such as in neon signs.


Is argon a stable element?

Yes, it is but I can't recall why but mark my words it is stable


Is a Helium a stable?

yes..


How chemically active are halogens?

Halogens are highly chemically active due to their strong tendency to gain an electron to achieve a full outer electron shell. They readily form compounds with other elements, particularly metals, through processes such as ionic or covalent bonding. Halogens can react vigorously with certain substances, making them important for various chemical applications.


When an electron moves from the outer shell of one element to the outer shell of another element what kind of bond has been created?

This is an ionic bond.


Is xenon a trasnsition element?

No, xenon is not a transition element. It is classified as a noble gas because it has a full outer electron shell, making it chemically inert. Transition elements are typically found in the d-block of the periodic table and have partially filled d orbitals.
