Write any 5 Properties of Hydrogen.✔✔

Thanks ❤ ​

Answer 1

Properties Of Hydrogen.

1) Hydrogen is the lightest element and will explode at concentrations ranging from 4-75 percent by volume in the presence of sunlight, a flame, or a spark.

2) Despite its stability, hydrogen forms many bonds and is present in many different compounds.

3) Three naturally occurring isotopes of hydrogen exist: protium, deuterium, and tritium, each with different properties due to the difference in the number of neutrons in the nucleus.

4) Hydrogen is the smallest chemical element because it consists of only one proton in its nucleus. Its symbol is H, and its atomic number is 1. It has an average atomic weight of 1.0079 amu, making it the lightest element

5) Hydrogen has one one proton and one electron; the most common isotope, protium (1H), has no neutrons

Hope this helps ☺️☺️☺️
