WebbA covalent bond is a chemical bond formed by shared electrons. Valence electrons are shared when an atom needs electrons to complete its outer shell and can share those electrons with its neighbor. The electrons are then part of both atoms and both shells are filled. Metallic bond. WebbAdult Education. Basic Education. High School Diploma. High School Equivalency. Career Technical Ed.
