What is characteristic of a covalent bond?A.Electrons are transferred from one nucleus to another.B.Electrons are shared between two different nuclei.C.Electrons are attracted to an atom on another molecule.D.Electrons are free to move among many nuclei.
Solution
The characteristic of a covalent bond is B. Electrons are shared between two different nuclei.
Here's a step-by-step explanation:
-
A covalent bond is a type of chemical bond where two atoms are connected to each other by the sharing of two or more electrons.
-
The electrons that participate in the covalent bonds are called 'shared pairs' or 'bonding pairs'.
-
This sharing of electrons allows each atom to attain a full outer shell of electrons and achieve stability.
-
Therefore, the characteristic of a covalent bond is not about transferring electrons from one nucleus to another (which is characteristic of ionic bonds), nor about electrons being attracted to an atom on another molecule or being free to move among many nuclei (which is characteristic of metallic bonds).
-
So, the correct answer is B. Electrons are shared between two different nuclei.
