The atomic number of an Element refers to it's position in The Periodic Table. The first element (Hydrogen - H) has the atomic number 1. The second element (Helium - He) has the atomic number 2. The fifty-second element (Tellurium - Te) has the atomic number 52. And so on.
Neon (Ne) in the second period on the periodic table of the elements has the highest atomic number in that period of 10.
Atomic number 2 corresponds to the element Helium. Helium has 2 protons in its nucleus, making it the second element on the periodic table. It is a colorless, odorless gas and is the second most abundant element in the universe.
The metal in the second period with one outer electron is lithium (Li). It is located in Group 1 of the periodic table, which consists of alkali metals. Lithium has an atomic number of 3 and is known for its light weight and use in batteries.
Helium has the atomic number 2 and is the second most abundant substance in the universe.
Francium is a highly radioactive alkali metal element with the atomic number 87 and symbol Fr. It is the second rarest naturally occurring element in the Earth's crust and is extremely unstable, making it difficult to study. Francium was discovered in 1939 by Marguerite Perey.
