How much does does the enthalpy change when you increase 5g of aluminum 10 degrees Celsius?

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.

14 days is the half-life of phosphorus-32

i think its 5049.

i hope this !
