Question

2. Write the chemical properties of Hydrogen.
​

Answer 1

Answer:

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. ... Hydrogen has a melting point of -259.14 °C and a boiling point of -252.87 °C. Hydrogen has a density of 0.08988 g/L, making it less dense than air.

Answer 2

$\small\mathbf\orange{{Chemical \: Properties \: of \: Hydrogen : }}$

• At standard temperature and pressure, hydrogen is a nontoxic, nonmetallic, odorless, tasteless, colorless, and highly combustible diatomic gas with the molecular formula H2.
• Common hydrogen has a molecular weight of 2,01594 g. As a gas it has a density of 0.071 g/l at 0ºC and 1 atm.
• Its relative density, compared with that of the air, is 0.0695.
• Hydrogen is the most flammable of all the known substances.
• Hydrogen is slightly more soluble in organic solvents than in water. Many metals absorb hydrogen.
• Hydrogen absorption by steel can result in brittle steel, which leads to fails in the chemical process equipment.
