Hydrogen is a nonmetal and is placed above group in the periodic table because it has ns1 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.Aug 15, 2020
Electronic Configuration: 1s
At Room Temperature: Colorless & Odorless Diatomic Gas
Atomic Weight: 1.0079
Nitrogen, oxegyn, and water are nonmetals in the atmosphere and combinations are essential for life on earth
Acid + alkali ------> salt + water
2KOH + H2SO4 ------> K2SO4 + 2H2O
Hope it helped!
If you can a number of electrons in a atom you will get a ion of the element
