What is group 1 or the alkali metals

400

This is why the size of the atom gets bigger as we go down the periodic table.

What is we are adding a energy level as we go down the periodic table

500

This element has an electron configuration that ends in the s orbital.  It forms sigma bonds only.  It has a low atomic mass number.  When combined with Oxygen it forms one of the most unique compounds known to man.  The compound has a very high boiling point for its atomic mass.  There is a type of bonding named after this element.  

What is Hydrogen

Organic

100

This type of hydrocarbon forms only single bonds and uses the formula H_2n+2

Explain the atomic production of light

When electrons are excited they jump up an energy level, but they are not stable, so they come back down and give off light.
