Chemistry Test: Covalent Bonding Practice Questios! Quiz
A covalent bond is a chemical link that encompasses the allocation of electron pairs between atoms. These electron pairs are recognized as shared pairs or bonding pairs, and the constant stability of attractive and repulsive forces in the middle of atoms when they share electrons is known as covalent bonding. This quiz will facilitate you getting ready for your chemistry test on covalent bonding. Make sure to take your certificate when you have completed the quiz.
