Two oxygen atoms combine to form a molecule by sharing electrons
The need for an electron determines whether an atom will form bonds. There must also be an electron available to meet the need of the atom.
The number of electrons in the outer shell. They will allow the atom to form covalent or ionic bonds, or no bonds at all.
electronegativity
valance
The number of electrons in an atom's valence shell determines its valency.
The number of unpaired electrons in the outermost shell determines the number os covalent bonds an atom can form.
The number of electrons in the atoms outer shell.
Directly it is the electrons. Indirectly the number of protons in the nucleus which determines how many electrons there are in the neutral atom and is a major determinant of ionization energy, electron affinity etc. which influence the formation of the bonds.
If an atom is electropositive (metals, in general), then they will lose electrons and form positive ions. If an atom is electronegative (non-metals, in general), then they will gain electrons and form negative ions.
The number of electrons in an atom's valence shell determines its valency.
valance
The largest determinant to an atom's behavior is its electron configuration. An atom's electron configuration determines its interactions with other atoms, such as which atoms it can form bonds with and whether that bond is covalent or ionic. Additionally, the number of neutrons and protons influence the stability of the atom's nucleus.

Generally, what determines whether atoms will form bonds is the atoms' relative propensity to donate and accept electrons and the activation energy of bond formation relative to the free energy available in the system. This applies to all potential reactants, and for any types of bonds.
Carbon form generally covalent bonds; ionic bonds are rare.
If an atom is electropositive (metals, in general), then they will lose electrons and form positive ions. If an atom is electronegative (non-metals, in general), then they will gain electrons and form negative ions.
How many bonds can atom form? not have ok so its answer is atoms are polygomus..they can make as many bonds as they desire . By its valence number. Remember the octet rule, atoms form bonds in order to have eight electrons in their outer shell (with the exception of hydrogen and helium.) Atoms can form multiple covalent bonds if they need more than one electron to complete their valence shells. Oxygen, for example, bonds with itself to form 2 bonds between the atoms (since each atom needs to share 2 electrons). i have given three answers so ithink you can now better understand
A chlorine atom can form ionic bonds by accepting an electron and covalent bonds by sharing electrons.
Covalent bonds form between nonmetals, the electronegativity of each atom determines what type of covalent bond (polar or nonpolar) is formed.
