Periodic Table - First Three Elements #6527572

Description

An image of the first three elements from the Periodic Table: Hydrogen, Helium and Lithium. Each element is 3 MP in dimension. Using hydrogen as an example: Number 1 represents the number of protons one hydrogen atom has and 1.0079 is its atomic mass. Unique fact: a hydrogen atom has only one electron - hence it is an extremely unstable element.
