The standard state, or reference state, of an element is defined as its thermodynamically most stable state at 1 bar at a given temperature (typically at 298.15 K). In thermochemistry, an element is defined to have an enthalpy of formation of zero in its standard state. For example, the reference state for carbon is graphite, because it is more stable than the other allotropes.

Which element is a stable element?
Helium is a stable element because it has a full outer electron shell, making it very unreactive with other elements.
What is the largest natural stable element?
The largest natural stable element is bismuth with atomic number 83. It is the heaviest element that is stable and does not undergo radioactive decay.
The Physical state of astatine?
Astatine is a halogen element that exists as a solid at room temperature. It is a very rare and radioactive element, with a half-life of only a few hours for its most stable isotopes.
Is carbon a more stable element than silicon?
Silicon is more stable.
Cerium is stable in 4 oxidation state?
Cerium is known to exist in the +3 and +4 oxidation states. In its +4 oxidation state, cerium is relatively stable due to its half-filled f-orbital, which provides additional stability. This makes cerium a unique element as most lanthanides almost exclusively exhibit a +3 oxidation state.
Which element is a stable element?
Helium is a stable element because it has a full outer electron shell, making it very unreactive with other elements.
What is the form of a element that is progressing toward a more stable state by emitting radiation is called?
The process of an element progressing toward a more stable state by emitting radiation is called radioactive decay. This results in the emission of energy or particles from the unstable nucleus in order to achieve a more balanced and stable state.
Which of the elements is stable?
a stable element is an element which have been able to complet its octect rule, i.e the electron of its outermost shell is complet, this is what is called a stable element
Is element fluorine stable?
Fluorine is a stable element.yes.
How does an atom of a representative element achieve its most stable state?
The valence shell must be completed to eight electrons.
What makes gold a stable element?
Gold is a stable element because of its unique electronic configuration, which means it does not readily react with other elements or chemicals like oxygen and water. Additionally, gold has a high density and melting point, which contribute to its stability and resistance to corrosion.
When an element has the same number of protons and electrons the element is a?
the element is stable.
Is the krypton element stable or unstable?
Krypton is a stable element. It is a noble gas found in the periodic table and does not readily react with other elements. Its stable configuration of electrons makes it inert and non-reactive.
Is oxygen chemically stable?
it's stable, but it is a reactive element!
Is Indium Stable?
Yes, the element indium is quite stable.
What is an element that is stable?
argon
Is cobalt a stable element?
No its not.
