Hydrogen Helium Lithium Table

Position of Hydrogen in the Periodic Table. So if you glance at the periodic table, you will see hydrogen is the first element in the table. It is the smallest element on the table. It has atomic number one, which means it has only one electron orbiting it its shell. In fact, Hydrogen has only one shell. Interactive periodic table with up-to-date element property data collected from authoritative sources. Look up chemical element names, symbols, atomic masses and other properties, visualize trends, or even test your elements knowledge by playing a periodic table game! Use the periodic table to look up the atomic numbers for the elements of hydrogen, helium, lithium, and beryllium. Complete the data table below and answer the follow-up question belo 5. Hydrogen Helium Lithium Beryllium What statement can be made about an element's atomic number and the number of protons in one atom of the element? 1 Hydrogen is the challenge. It acts as both contributing (Column 1 at the left) or receiving (Column 17 at the right) equally easily. Nothing else can do both that easily. It has the narrowest liquid range of any element and, in liquid form, has over 40 times the refrigerating capacity of liquid helium and three times that of liquid hydrogen. Neon has a very high ionisation energy (2080.7 kJ/mol), low electron affinity (estimated at −120.
