how is electronegativity related to covalent bonding? atoms must have similar electronegativities in order to share electrons in a covalent bond. atoms must have very different electronegativities in order to transfer electrons in a covalent bond. atoms must have similar electronegativities in order to transfer electrons in a covalent bond. atoms must have very different electronegativities in order to share electrons in a covalent bond.
Answer
Brief Explanations:
Covalent bonding involves sharing of electrons. When atoms have similar electronegativities, neither atom has a strong enough pull to take electrons from the other, so they share electrons. When electronegativities are very different, electron - transfer (ionic bonding) is more likely.
Answer:
Atoms must have similar electronegativities in order to share electrons in a covalent bond.
