The most thermally stable carbonate in Group 1 elements is lithium carbonate (Li2CO3) because it has the smallest cation size, which results in stronger ionic bonding and lower polarizability. This makes it less prone to thermal decomposition compared to the carbonates of other Group 1 elements like sodium and potassium.

Is carbonate CO3 a stable compound?

Carbonate is not a compound at all, because it is not electrically neutral; instead it is a polyatomic ion, with a charge of -2. Most carbonate salts are stable at standard temperature and pressure, but most of them will convert from carbonates to oxides by releasing carbon dioxide when heated sufficiently.


What is the most stable group on the period table known as?

The noble gases are the most stable group on the periodic table. They have a full outer electron shell, making them unreactive and chemically stable.


Where are Stable Elements in the periodic table located?

Stable Elements in the periodic table are located in Group 18 of the periodic table.It is a group of noble gases.Noble gases are considered most stable in nature.


What is the most stable element group?

The noble gases, also known as Group 18 on the periodic table, are considered the most stable element group. They have a full outer electron shell, making them unreactive and chemically stable.


What is the most active group in periodic table?

Group-18 family is the most inactive family. It is stable and hence non reactive.

What is the most stable confirmation of cyclohexane?

The most stable conformation of cyclohexane is the chair conformation. In this conformation, all carbon atoms are in a staggered position and there is minimal steric hindrance between the hydrogen atoms. This results in the lowest energy state for the molecule.


Are the most stable elements you the periodic table are found in the family of alkali metals?

No, the most stable elements on the periodic table are typically found in the noble gas family. Alkali metals, such as lithium and sodium, are relatively reactive compared to noble gases like helium and neon, which have full valence shells and are therefore more stable.


Which family is the most stable elements?

The noble gases (Group 18) are the most stable elements because they have a full outer electron shell, making them chemically inert and unlikely to form compounds with other elements.


How many electrons do the elements of the most stable group have in their outer layer?

Eight, except for helium which has two.
