Covalent Bonding

Covalent Bonding

Covalent Bonding. …electrons are shared. How does H 2 form?. The nuclei repel. But they are attracted to electrons. They share the electrons. +. +. Covalent bonds. Nonmetals hold onto their valence electrons. They can’t give away electrons to bond. Still want noble gas configuration.
