Answer:
Covalent bonds involve the sharing of electron pairs between atoms. Electron pairs shared between atoms of equal or very similar electronegativity constitute a nonpolar covalent bond (e.g., H–H or C–H), while electrons shared between atoms of unequal electronegativity constitute a polar covalent bond (e.g., H–O).

Explanation:
Answer:
700,000 holes
Explanation:
When heat energy occurs to produce free electrons, the number of free electrons produced is directly proportional and equal to the number of holes it produces at that time.
Hence, if silicon crystal (pure) has 700,000 free electrons, then the number of holes it have is also 700,000.
