If the original experiment is repeated but 100 gg of the 0∘c∘c water is replaced with 100 gg of 0∘c∘c ice, what is the final temperature of the water and block?.

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.
