What do the numbers mean on the periodic table of elements?

Here’s a look at what they mean and where to find important elements. One number you will find on all periodic tables is the atomic number for each element. This is the number of protons in the element, which defines its identity.

What is the first element in Group 2 on the periodic table?

Beryllium is the first element in group 2. Helium is the first element in group 18. The rows of the periodic table are called periods. Most periodic tables do not number them because they are fairly obvious, but some tables do. The period indicates the highest energy level attained by electrons of an atom of the element in the ground state.

What is the most obscure element on the periodic table?

Perhaps its greatest claim to fame on the periodic table is that it defines the start of the most obscure of the artificial elements – those above 100 are referred to as the transfermium elements. It is certainly the highest numbered element that has had a practical use identified.
