n an alien world, a different periodic table exists. It is organized similar to the periodic table in our world, just smaller. The first group contains the alkali metals, the second group the alkaline earth metals, there are a few transition metals, and then some non-metals. And there is still hydrogen, which is used to make acids. The periodic table is shown below in picture form, and a table is given with molar masses and common ionic charges. Also in the table is a list of common ion groups (similar to carbonate, nitrate, etc. in our world.)

The chunk of sodium has a mass (in kilograms) equal to the atomic number of fluorine. A tremendous explosion follows emitting light and heat able to be observed from a drone flying at an altitude of approximately 53 m. How many atoms of sodium from the original chunk remain in Wisconsin after the reaction is complete? This is an MCAT style question.

Mendeleev left empty spaces in his periodic table for elements he suspected existed but had yet to be discovered. He left no spaces for the Noble gases that we now have in the modern periodic table. Give at least two reasons on why this group was challenging to discover, based on what we now know about the atom including sub-atomic particles. Mendeleev had a group VIII but they are NOT the noble gases.
