Q: Q: Because the nuclei of each h atom contain protons, the electrons in the bond are attracted to the nuclei (opposite charges attract). but because the two atoms involved in the covalent bond are both h atoms, each nucleus attracts the electrons by the same amount. thus the electron pair is equally shared by these? Read this paragraph and choose the correct option from the provided answers: Because the nuclei of each H atom contain protons, the electrons in the bond are attracted to the nuclei (opposite charges attract). But because the two atoms involved in the covalent bond are both H atoms, each nucleus attracts the electrons by the same amount. Thus the electron pair is equally shared by the two atoms. The equal sharing of electrons in a covalent bond is called a nonpolar covalent bond. Now consider the HF molecule:. Choices: - four atoms - one atom - nine atoms - two atoms A:
A: two atoms
