What else can I help you with?
Why is the noble gases the most stable?
Their valence shells are completely full, so they are least likely to be reactive and are thus most stable.
What are the least reactive that have full valence shells?
Inert gases
Which of the nonmetals is the least reactive?
The Noble Gases.
Are nonmetals least reactive?
Some are but the most reactive are also non-metals.
Which group of nonmetals is the least reactive?
The Noble Gases.
Are the halogens most reactive nonmetals or the least reactive nonmetals?
The Halogens are the most reactive non-metals. However, their reactivity decreases as you go down the group. Most reactive Fluorine>Chlorine>Bromine>Iodine>Astatine Least reactive. However, Astatine is not fully characterised because it is radio-active, and consequently is not found in open(school) labs.
Are Noble gases most reactive element on the periodic table?
No. They are the least because their energy levels are full.
What are the ranks of the periodic table families from most to least reactive?
Most reactive metals are alkali metals, most reactive nonmetalas are halogens.Least reactive metals are platinum metals; least reactive nonmetals are noble gases.
Does group 7A of the periodic tables contain the least reactive nonmetals?
No, Group 8A (Noble Gases) are the least reactive nonmetals because they have a full outer shell of electrons and do not readily form chemical bonds. Group 7A (Halogens) are more reactive in comparison.
Which group on the periodic table contains the least reactive nonmetal?
The least reactive nonmetals are found in Group 18 of the periodic table, known as the noble gases. This group includes elements like helium, neon, and argon, which have a full valence shell of electrons, making them very stable and largely unreactive. Among them, helium is often considered the least reactive due to its small size and complete electron configuration.
Which list has the classes of elements in order from most reactive to least reactive?
The order of reactivity among classes of elements typically follows this pattern: alkali metals (most reactive), alkaline earth metals, transition metals, metalloids, nonmetals, and noble gases (least reactive). Alkali metals, such as lithium and sodium, readily lose electrons, making them highly reactive, especially with water. Alkaline earth metals are also reactive but to a lesser extent, while noble gases are largely inert due to their complete electron shells.
What these nonmetals which one is likely to be the least reactive nitrogen (N) phosphorous (P) sulfur (S) oxygen (O)?
Nitrogen (N) is likely to be the least reactive among the nonmetals listed. It is a diatomic gas with a stable triple bond that makes it less reactive compared to phosphorus (P), sulfur (S), and oxygen (O) which are more readily reactive due to their lower bond strengths.
