Which is a column running up and down in the periodic table?

the answer is false because not all countries have geysers under their crust. for example, iceland uses geothermal energy because it is available every in their country.  

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.
