HE-LI-UM 
Let's finish off the top row of the periodic table with a short look at helium. You'll find it on the upper right of the table as element number two. Helium is the other very simple element that you will find with one atomic orbital. The chemists Lockyear and Frankland named the element. They named it after the Sun and the Latin word "helios". Even when first discovered and identified, scientists knew there were large amounts of helium in the Sun. Similar to hydrogen, helium is usually found as a gas and has no color or smell. Helium is found everywhere in the universe and is the second most common element, just like hydrogen.
