When it's outer electron shell is full and it is in a cold (like near 0K) environment.
the valence shell is full of elctrons

Chemical bonds that are least ionic are covalent bonds.
At least one electron from one of the atoms is transferred from an orbital where it occurs in a single atom to either an orbital in one of the other atoms, forming an ionic bond between the two atoms, or to a different orbital that can exist only under the influence of two atoms, forming a covalent bond between the two atoms. In the latter instance, but not the former, the atoms bonded can be atoms of the same element.
The type of bond that usually occurs between molecules is the hydrogen bond. It is the result of an attraction between two electronegative atoms involving a hydrogen atom between them.
A covalent bond is the strongest of the four types of chemical bonds, as it requires two atoms to share at least one electron each to form full electron shells.
the element
Chemical reactions always involve changes in the chemical bonds that join atoms in compounds. At least one chemical bond is broken or formed during a chemical reaction.
This is a molecule.
Helium, neon and argon are the least likely elements to form compounds.
The atom is the smallest unit of an element that retains the chemical properties of that element. A molecule is defined as a unit of at least two atoms held together by very strong chemical bonds.
Chemical bonds that are least ionic are covalent bonds.
Helium.
An atom is a particle which makes up an element. When an atom reacts with another atom, they create a chemical bond. When this happens, the elements made from these atoms make a compound. Example: 2 Hydrogen atoms + 1 Oxygen atom ---> water (H2O)
Atoms do not have bonds. Only compounds have bonds. it takes at least two atoms to have a bond.
In chemistry, a molecule is defined as a sufficiently stable electrically neutral group of at least two atoms in a definite arrangement held together by very strong chemical bonds. It can also be defined as a unit of two or more atoms held together by covalent bonds.
An unsaturated fat contains at least one double bond.However, the majority of the carbon-carbon bonds even in polyunsaturated fats are single bonds.
At least one electron from one of the atoms is transferred from an orbital where it occurs in a single atom to either an orbital in one of the other atoms, forming an ionic bond between the two atoms, or to a different orbital that can exist only under the influence of two atoms, forming a covalent bond between the two atoms.
