How much heat, in kj, is required to melt 54.0 g of ice at 0°c into water at 0°c if hfus for water = 6.01?

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.

i think its 100.

hope this !
