What effect does nuclear radiation have on atoms? it splits atoms. it burns atoms. it ionizes atoms.

It ionizes atoms.  

Step-by-step explanation:

There are three types of nuclear radiation:

α rays β rays γ rays

All of these have enough energy that they can remove an electron from an atom and cause it to become charged or ionized.

A is wrong. Ionizing radiation does not have enough energy to split atoms.

B is wrong. Nuclear radiation does not involve burning — the reaction of atoms with oxygen.

I'm pretty sure the answer is alcohol 

So the main goal for the elements is stability which is a complete/full valence shell and typically the magic number for a stable element is 8 valence electron but not always. so elements to the left of the periodic table tend to be way less stable then those on the right, so the elements on the left are much more reactive.
