Question

Chemical bond formed when one or more electrons are transferred from one atom to another

Answer 1

i believe thats an ionic bond

Answer 2

If the electron is shared equally between the atoms , it is a covalent bond.
An ionic bond, are atoms that are bound together by the attraction between oppositely-charged ions.

Another thing that must be recognized is that covalent bonds are between two nonmetals while ionic is between a metal and nonmetal.

non metal + non metal = covalent (sharing of bonds)
metal + non-metal = ionic (giving away of electrons by one and receiving by the other)
