If a chemical reaction such as photosynthesis begins with 6 atoms of carbon (c), how many atoms of carbon (c) should be in the products? a. 12 atoms of carbonb. 6 atoms of carbonc. 3 atoms of carbond. 2 atoms of carbon

B.  6 atoms of C. That's the answer

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
