In oth­er words, the greater the vol­ume of hy­dro­gen, the low­er the con­cen­tra­tion re­quired for an ex­plo­sion. Con­se­quent stud­ies on the re­ac­tion be­tween oxy­gen and hy­dro­gen have as­cer­tained that large vol­umes of hy­dro­gen can be ex­plo­sive even at small con­cen­tra­tions. Hy­dro­gen gas is high­ly flammable and will burn in air at an ex­treme­ly wide range of con­cen­tra­tions (be­tween 4% and 75% by vol­ume). Oxy­hy­dro­gen is most ex­plo­sive at a hy­dro­gen:oxy­gen ra­tio of 2:1, also known as Brown's Gas, or 2:5 for hy­dro­gen and air. The tem­per­a­ture of the hy­dro­gen-oxy­gen flame reach­es over 2,000 ☌.Īs we know, a mix­ture of hy­dro­gen and oxy­gen forms oxy­hy­dro­gen - an ex­plo­sive mix­ture.

The com­bus­tion of hy­dro­gen is ac­com­pa­nied by the re­lease of a large amount of heat. The hy­dro­gen con­tin­ues to burn, and the walls of the flask are cov­ered with drops of wa­ter that form as a re­sult of the re­ac­tion be­tween hy­dro­gen and oxy­gen. The stream of burn­ing hy­dro­gen is then di­rect­ed into a flask con­tain­ing oxy­gen. The fol­low­ing is a com­mon demon­stra­tion of the re­ac­tion be­tween hy­dro­gen and oxy­gen:Ī stream of pure hy­dro­gen re­leased from a gas tube is ig­nit­ed in air, and the gas burns with an even, al­most un­no­tice­able flame. When hy­dro­gen is heat­ed, a com­bi­na­tion re­ac­tion takes place be­tween the el­e­ment and sim­ple sub­stances such as chlo­rine, sul­fur, and ni­tro­gen. Hy­dro­gen’s re­ac­tions with sim­ple sub­stances its crys­tal struc­ture is molec­u­lar and breaks down eas­i­ly due to weak bonds be­tween the lat­tice nodes.hy­dro­gen is 14.5 times lighter than air.it dis­solves well in some met­als be­cause of its abil­i­ty to dif­fuse through them.hy­dro­gen is in­sol­u­ble in wa­ter, so it can be ob­tained in a lab­o­ra­to­ry set­ting via the elec­trol­y­sis of wa­ter (the de­com­po­si­tion of wa­ter into oxy­gen and hy­dro­gen).in spe­cial con­di­tions, hy­dro­gen is ca­pa­ble of as­sum­ing a metal­lic state.at high pres­sures, hy­dro­gen forms sol­id, snow-like crys­tals.in nor­mal con­di­tions, hy­dro­gen is a col­or­less, odor­less, taste­less gas that is both com­bustible and ex­plo­sive.

liq­uid hy­dro­gen can se­vere­ly freeze the skin upon con­tact.Hy­dro­gen as a pure sub­stance has the fol­low­ing phys­i­cal pa­ram­e­ters: Hy­dro­gen is a chem­i­cal el­e­ment un­like any oth­er, with spe­cial prop­er­ties of enor­mous sig­nif­i­cance. As such, hy­dro­gen is rec­og­nized as a stan­dard of light­ness. hy­dro­gen’s low atom­ic mass makes it the light­est el­e­ment.Due to this prop­er­ty, hy­dro­gen con­ven­tion­al­ly be­longs to the halo­gen group when in­ter­act­ing with strong re­duc­ers (such as al­ka­li met­als), hy­dro­gen be­comes an ox­i­diz­er, ac­cept­ing an elec­tron.hy­dro­gen is a good re­duc­er, and so is in sub­group A of the first group.

If it sur­ren­ders its elec­tron, hy­dro­gen is left with a free or­bital, which can form chem­i­cal bonds ac­cord­ing to a donor-ac­cep­tor mech­a­nism as its out­er lev­el only con­tains 1 elec­tron, hy­dro­gen has both ox­ida­tive and re­duc­tive prop­er­ties.Their prop­er­ties are very dif­fer­ent – for hy­dro­gen, even adding just one AMU (atom­ic mass unit) means dou­bling its mass Hy­dro­gen has 3 iso­topes with mass­es of 1, 2, and 3. hy­dro­gen has an atom­ic num­ber of 1, and has 1 elec­tron and 1 pro­ton.Hy­dro­gen’s main prop­er­ties, as can be de­ter­mined from its po­si­tion as the first el­e­ment in the pe­ri­od­ic ta­ble, are as fol­lows:
