C) attractive; nucleus; repelling
D)attractive; electrons; repelling

Explain answer.

Answer 1

The correct answer is:

D) attractive; electrons; repelling

Explanation:

• Covalent bonds form when the attractive forces between the electrons of two atoms are greater than the repelling forces between their nuclei.
• Electrons are involved in covalent bonding by being shared between atoms, which creates a stable configuration.
• The repelling forces occur between the negatively charged electrons of each atom and the repulsion between the nuclei of the atoms, which are both positively charged.
