Answer :
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.
