HELP! Determine the total kilojoules in two tablespoons of crunchy peanut butter that contains 6 g of
carbohydrate, 16 g of fat, and 9 g of protein.
Express your answer to two significant figures and include the appropriate units.

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.
