carbon has an atomic number of 6. the number of electrons found in the first shell is:
o two.
o four.
o six.
o eight.

Explanation:

Question 13

Catabolic processes break down molecules. Hydrolysis breaks polymers into monomers (catabolic). Dehydration synthesis and peptide bond formation build molecules (anabolic). So hydrolysis is catabolic.

Subatomic particles: orbitals are electron regions, protons are positive (nucleus), neutrons are neutral (nucleus), electrons are negative and orbit the nucleus.

Atomic electron shell rules: first shell holds max 2 electrons. Carbon (atomic number 6) has 2 in first shell, 4 in second.

Answer:

Hydrolysis (the first option)
