The most recent accurate answer would be Neon. At least that's what my memory ( and my Periodic Table of the elements) tells me. If I am not correct please let me know!
All elements in the 7th family/group (2nd from the right) on the Periodic Table.
Electrons.
electronegativity
They have a covalent bond
The bond between an electropositive atom (which tends to lose electrons) and an electronegative atom (which tends to gain electrons) is ionic in nature because it involves the complete transfer of electrons from one atom to another. The electropositive atom donates one or more electrons, resulting in a positively charged ion (cation), while the electronegative atom accepts those electrons, forming a negatively charged ion (anion). The electrostatic attraction between these oppositely charged ions creates a strong ionic bond, leading to the formation of ionic compounds. This type of bonding typically occurs between metals and nonmetals.

Electrons.
When an atom combines chemically with another atom, it either gains, loses, or shares electrons to achieve a more stable configuration. This process results in the formation of chemical bonds, which can be ionic or covalent depending on how the electrons are shared or transferred between the atoms involved.
A sulfur atom tends to gain two electrons to achieve a stable electron configuration when bonding with another atom to form an ionic compound. This results in the formation of a sulfide ion, which has a negative charge.
Atoms will form an ionic bond when one atom donates an electron to another atom. Typically, this occurs between a metal atom (which tends to lose electrons to form positive ions) and a non-metal atom (which tends to gain electrons to form negative ions).
Ionic bonds form between atoms when one atom donates an electron to another atom, resulting in the formation of positively and negatively charged ions that are attracted to each other. This typically occurs between a metal atom (that tends to donate electrons) and a nonmetal atom (that tends to accept electrons).
An ionic bond is formed through the transfer of electrons from one atom to another. This transfer occurs between a metal atom (that tends to lose electrons) and a nonmetal atom (that tends to gain electrons). The resulting attraction between the positively charged metal cation and the negatively charged nonmetal anion forms the ionic bond.
electronegativity
Ionic bonds form in an ionic compound when one atom transfers electrons to another atom, resulting in the formation of positively and negatively charged ions. The opposite charges attract each other, creating a strong electrostatic force that holds the ions together in a stable structure. This transfer of electrons occurs between a metal atom (which tends to lose electrons) and a nonmetal atom (which tends to gain electrons).
When two (or more atoms) join to form a compound, they actually join by sharing electrons.
They have a covalent bond
An oxygen atom can share up to two electrons to form a covalent bond with another atom. This is because oxygen has six valence electrons and can complete its octet by sharing two electrons with another atom.
