The specific heat of Aluminum is 0.897 J/g°C. If we are using 75J of energy to heat a piece of aluminum foil that weighs 8.5g, what is the resulting change in temperature?

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.
