Is iron more common than hydrogen and helium
Witryna15 sie 2024 · Properties of Hydrogen . Hydrogen is a nonmetal and is placed above group in the periodic table because it has ns 1 electron configuration like the alkali metals. However, it varies greatly from the alkali metals as it forms cations (H +) more reluctantly than the other alkali metals.Hydrogen‘s ionization energy is 1312 kJ/mol, … Witryna29 kwi 2024 · Reactivity and Availability. As similar as they are in size, in most other ways helium and hydrogen couldn’t be much more different than one another. Hydrogen’s relentless quest to acquire a second electron makes it highly reactive as a lone atom. Even when bonded to another atom of hydrogen, the resulting H 2 molecule is still …
