Answer:
1) four valence
Atomic carbon has six electrons: two inner shell (core) electrons in the 1s orbital, and four valence (outer most shell) electrons in the 2s and 2p orbitals.
2) four
To achieve stability, carbon must find four more electrons to fill its outer shell, giving a total of eight and satisfying the octet rule. Carbon atoms may thus form bonds to as many as four other atoms.
3) THREE or at most FOUR BONDS
So it can form three, or at most four bonds. Oxygen needed for Carbohydrates and Carbon Dioxide forms two bonds. Hydrogen needed for Carbohydrates can form one bond. Sulfur used in making some amino acids can form 2 , 4 or 6 bonds.
