The periodic table shows all the elements and their physical properties it is arranged based on atomic numbers and electron arrangement. On the Periodic table there are mass numbers, mass numbers are the total of the protons and Neutrons present in the nucleus of the atom there are also

What are Alkali metals?

Alkali metals sit in level one on the periodic table, they also react with everything because they only have one electron in there outer shell. 

What did we see during the experiment?

When the alkaline metal was added to the cold water and the universal indicator. Then it started to float around once it floated around for a bit it caught on fire. It caught on fire because the metal only has one electron in its outer shell so the metal reacted to get rid of its electrons.
