Hemoglobin is a protein made of thousands of atoms. Using chemical bonds such as covalent and ionic bonds, these atoms are
arranged in a very specific structure. What is the difference between covalent and ionic bonds? (1 point)
A. Covalent bonds occur when electrons are shared by two nonmetals. Ionic bonds occur when electrons are shared between two metals.

B. Covalent bonds occur when electrons are shared by two nonmetals. Ionic bonds occur when an electron is donated by a metal to a
nonmetal
C. Covalent bonds occur when an electron is donated by a nonmetal to a nonmetal. Ionic bonds occur when electrons are shared by a metal
and a nonmetal
D. Covalent bonds occur when an electron is donated by a meta a nonmetal. Ionic bonds occur when electrons are shared by two
nonmetals
