Electrons are unequally shared, they are pulled towards the more electronegative element . Difference electronegativity less than 1.9 unit
Covalent bonds form betweenthe electrons in the outer valence of an atom.Read more: What_do_covalent_bonds_usually_form_between
Ionic bonds are bonds formed by a metal and a nonmetal (e.g. CaCl2), while covalent bonds are bonds formed between two nonmetals (e.g. CO2).
If electronegativity varies by more than 1.4 then you are most probably looking at an ionic bond. A variance less than 1.4 means, usually a covalent bond can be formed. This is a rule of thumb and is not always reliable. Metal to nonmetal; ionic. nonmetal to nonmetal; covalent.
it depends if the formula. it is ionic if the bonds are formed between nonmetal and metals.
Covalent bonds tend to occur between two Non- Metals.
Covalent.
Metal atoms.

If the electrons are "stolen" from the metal by the nonmetal, an ionic bond is formed. If the electrons are shared between the metal and the nonmetal, a covalent bond is formed. If the electrons "resonate" between the metal and the nonmetal, a resonance bond is formed.
Ionic bonds are formed between a metal and a nonmetal.
The outer shell electrons of the atom form covalent bonds.
Ionic bonds are bonds formed by a metal and a nonmetal (e.g. CaCl2), while covalent bonds are bonds formed between two nonmetals (e.g. CO2).
A covalent bond is formed. A molecular compound is formed.
A covalent bond is formed. A molecular compound is formed.

Molecule. A nonmetal to nonmetal covalent bond. Electronegativity is not variant enough among the nonmetals to form ionic bonds.
