Multiple Choice
Which of the following best describes a covalent bond?
A
A bond formed by the attraction between oppositely charged ions
B
A bond formed by the overlap of atomic orbitals
C
A bond formed by the transfer of electrons from one atom to another
D
A bond formed by the sharing of electrons between atoms
Verified step by step guidance
1
Understand that a covalent bond is a type of chemical bond where two atoms share one or more pairs of valence electrons.
Recognize that this sharing of electrons allows each atom to attain the electron configuration of a noble gas, achieving greater stability.
Differentiate between covalent bonds and other types of bonds: ionic bonds involve the transfer of electrons, while metallic bonds involve a 'sea of electrons' shared among many atoms.
Identify that covalent bonds typically occur between nonmetal atoms, which have similar electronegativities, allowing them to share electrons rather than transfer them.
Conclude that the best description of a covalent bond is 'a bond formed by the sharing of electrons between atoms,' as this highlights the key characteristic of covalent bonding.
