A student initiates two chemical reactions by adding a different substance to each of two beakers with different solutions. She observes them for 10 minutes, recording the temperature of the solution in each beaker every minute. 1. Calculate What was the temperature change of each solution after 10 minutes?

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.
