On the periodic table, the elements in the left column, like Na (sodium) have only 1 electron in their outermost shell. This makes them

• extremely reactive, like with explosions

• a little reactive like the baking soda and vinegar reaction

• not very reactive, like they are the same as iron and aluminum

• not reactive at all, like kings and queens who don't want to meet their "little people"

On the periodic table, the column on the far right side is called noble gases, and they each have all 8 electrons in their outermost shells. This makes them....

• not reactive at all, like royalty that won't go out and meet their people

• a little reactive

• solids like iron

• so reactive they almost explode they react so fast

What is supposed to happen at absolute zero temperature?

• all particles stop moving completely.

• nothing

• all particles start moving extra fast

• your warmest coat won't keep you warm
