Hydrogen (symbol H) is element number 1 of the periodic table and belongs to the “Nonmetal” category. Its atomic mass is about 1.008, and its phase under standard conditions is Gas. This element sits in period 1 and group 1 of the periodic table, and its electrons are arranged in shells of 1. The short electron configuration of Hydrogen is 1s¹. Known uses of Hydrogen include Rocket fuel, Ammonia production and Hydrogenation of edible oils.
The electron configuration of Hydrogen (H), with 1 electrons, is shown below. The last shell (shell 1) is highlighted:
Distribution of 1 electrons of Hydrogen across shells K to K:
The nonmetals are usually poor conductors of heat and electricity and are brittle in solid form; they are the base elements of organic and biological chemistry.
The atomic number of Hydrogen (H) is 1; that is, every atom of it has 1 protons.
The electron configuration of Hydrogen (H) is 1s¹; in short form it is 1s¹, and its last shell is 1s¹.
