how is electronegativity related to covalent bonding?\natoms must have similar electronegativities in order to share electrons in a covalent bond.\natoms must have very different electronegativities in order to transfer electrons in a covalent bond.\natoms must have similar electronegativities in order to transfer electrons in a covalent bond.\natoms must have very different electronegativities in order to share electrons in a covalent bond.
Answer
Brief Explanations:
Covalent bonding occurs when atoms share electrons. Atoms with similar electronegativities share electrons because neither atom has a strong enough pull to take the electrons from the other. When electronegativities are very different, electrons are transferred (ionic - bonding), not shared.
Answer:
Atoms must have similar electronegativities in order to share electrons in a covalent bond.
