Yes, it has the atomic # of 20 on the periodic table of elements.
August 20, 1864 was when John Alexander Reina Newlands produced the first periodic table of the elements.
The first 20 elements of the periodic table are made up of a variety of elements including hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon, sodium, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, argon, potassium, and calcium.
Conductors in the first twenty elements include; Lithium - Li Beryllium - Be Carbon - C Sodium - Na Magnesium - Mg Silicon - Si Potassium - K Calcium - Ca
