The periodic table below shows each chemical element's name, atomic number, and atomic symbol.Use the periodic table to fill in the missing information in the table below.Name Atomic Symbol Atomic NumberHelium 2 Sn 50 20

Some elements have names that do not match their chemical symbols. We gave you one example earlier of silver, whose chemical symbol is AgAg. Research all the elements you can find that fit this description. Then in the space below, write out where their symbols originate from. A periodic table can be found here.

Use the periodic table and complete the following information todetermine the number of protons, neutrons and electrons andto know the identity of an atom
