In chemical compounds, covalent bonds form when

• the electronegativity difference between two atoms is very large.
• electrons are completely transferred between two metals.
• pairs of electrons are shared between two nonmetal atoms.
• two nonmetal atoms are attracted to each other by opposite charges.

An ionic bond forms when 

• Valence electrons are shared
• a sea of mobile electrons surround the cations
• valence electrons are transferred between atoms
• none of the above
