Sr has an atomic number of 38 so we'll start there.
The closest noble gas is Kr with an atomic number of 36 so it'll look like this:
[Kr]5s^2.
There are two atoms of hydrogen molecules.
Temperature is very important if ice gets too hot it turns to water, if it gets even hotter it turns to gas.
but if it’s too cold water can turn into ice
Temperature determines what state of matter something is
