An atom of argon rarely bonds to an atom of another element because an argon atom has what?
Atoms of argon have a full outer (valence) shell, and this is why argon is inert. The electrons of an atom have different energy levels. It's conventional to call each collection of possible states of electrons for a given energy level a shell. Shells have finite capacity and argon has a full outer shell. Chemical reactions tend to rely on electrons jumping from one atom to another or two sharing the orbit of 2 electrons (a type of shell around 2 electrons if you like). If the shells are full it is usually more energy efficient for an electron to stay put rather than jump to another atom. consequently argon with its full shells rarely bonds.
Why is group VIIIA called noble or inert gases?
According to the classical shell model for electrons, the group 18 elements have a fully filled outer shell, rendering them inert to most chemical reactions (little tendency to participate in chemical reactions ) they are called noble or inert gases
Why is the absorbance versus concentration curve rarely straight?
The absorbance versus concentration curve is rarely straight because the relationship between absorbance and concentration is not always linear. Factors such as non-linear interactions between molecules, chemical reactions, and instrumental limitations can cause the curve to be curved instead of straight.
What makes Noble gases different than any other element?
Noble gases differ from other elements in that the number of electrons that are attached to the core is exactly right. Most elements have either too much or too few electrons to fill their shells (rings of electrons surrounding the nucleus). Noble gasses therefore do not interact with other elements to shed, share or steal electrons like other elements do. Under normal conditions these gases do not react with any other element, and it is therefore that no one ever isolated a noble gas until 1895.
Why is an excess reagent frequently used in chemical reactions?
An excess reagent is often used in chemical reactions to ensure that the reaction goes to completion. This helps to maximize the yield of the desired product by ensuring that all of the limiting reagent is consumed. It also helps to compensate for any experimental errors and achieve better reproducibility in the reaction.
Why do noble gases rarely undergo chemical reactions?
Noble gases rarely undergo chemical reactions due to their complete valence electron shells, which make them chemically stable and less likely to form bonds with other elements. This full outer shell configuration results in a lower tendency to gain, lose, or share electrons, contributing to their inertness. Additionally, the high ionization energies of noble gases make it energetically unfavorable for them to participate in chemical reactions. Consequently, they are generally found in nature in their monatomic state.
How is the body able to cope with chemical changes?
They tries to adapt and digest otherwise they form malignant reactions rarely

Factors on which electronegativity?
Factors Affecting Electronegativity. Introduction. Is a chemical property that describes the ability of an atom (or, more rarely, a functional group) to attract electrons.
Why is group VIIIA called noble or inert gases?

Atoms that are known as inert or noble rarely undergo reactions because?
Noble gases are non-reactive due to their stability. The outer most shell shoud have 8 electrons to be stable and all the elements in the eighth group have 8 electrons in their outer most shell so they do not need to take part in chemical reactions to become stable THAT is why they are non reactive!
Why does neon rarely form compounds with other elements?
Neon rarely forms compounds with other elements because it already has a complete outer electron shell (8 electrons in total) in its natural state. This full shell makes neon very stable and unreactive, which means it does not readily participate in chemical reactions to form compounds.
How do the electron configurations of the noble gases make them all highly unreactive?
Noble gases have completely filled orbitals / electron energy shells. They are stable and chemically inert (non-reactive). So generally they will not accept / gain / share electrons and they do not form compounds.
Why does neon Ne rarely form compounds with other element?
Neon is unreactive because its valence shell is completely filled with eight electrons. Atoms undergo chemical reactions and form compounds in order to fill their outermost (valence) energy shell with eight electrons (two for helium, lithium, and beryllium). Having a filled valence shell makes an atom stable.
Which elements on periodic table undergo fewest chemical reactions?
The noble gases, such as helium, neon, and argon, undergo the fewest chemical reactions due to their stable electron configuration. They have a full outer electron shell, making them highly unreactive and rarely forming compounds with other elements.
Is a noble gas an unreactive gas?
Yes, they are. The noble gases (group 18) on the periodic table of elements are unreactive because they have 8 electrons on their outer shell (valence electrons) and therefore they are very stable. Due to this stability, they will rarely react with any other chemical.
Why is the reactivity of noble gases so low?
Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally do not form compounds under normal conditions.
