What is the difference between Helium & Hydrogen?

Question

Why is helium carries much less risk of explosion than hydrogen? please answer as soon as u can...

Answer 1

Um, let's see. If I remember my chem classes the biggest difference between the two is that extra electron orbiting the nucleus in the Helium atom.
As I remember that does two things: it 'fills up' the outer electron orbits of that nucleus and thus makes it a lot less 'hungry' so that it is far less likely to snatch or borrow another electron from some other atom ( like oxygen which has lots of spots free in it's outer electron shell making it an exceedingly 'hungry' atom and thus 'oxidizer') This means that helium won't combine with other atoms easily while hydrogen will.
The other thing that extra electron does to the helium atom is it makes it heavier than the hydrogen atom. Thus helium doesn't have quite as much 'lift' as hydrogen.
Oh, and hydrogen isn't the most dangerous thing loose out there. Oxygen combines with several things besides hydrogen. Hydrogen at least goes up and dissipates in the air while things like gasoline fumes and propane are heavier than air and tend to 'puddle' in explosive concentrations down at ground level.

Atomic Structure Of Helium

Answer 4

Hydrogen has one proton; helium has 2. additionally, helium has its final (its _only_, extremely) valence finished, so it can't bond clearly with the different aspects (it is why it extremely is an inert, or noble, gasoline). Hydrogen does not, so it may. This helps to describe why helium makes good blimp filler cloth and hydrogen makes the Hindenburg.

Answer 5

In fact, Helium is not explosive at all, at STP (standard temperature and pressure. Moreover, Helium is not flammable. It is one of the Inert gases; inert meaning not reactive at all. In contrast, Hydrogen is flammable. It reacts explosively with Oxygen (O2) ever present in air around us and in the presence of spark to form a stable end product, water.

Now, consider bottling (pressurizing in closed container) both gases under high pressure! Both will be explosive in case of improper handling and accidents, but the hydrogen has the added risk of fire and heat.

Answer 6

Helium is non reactive. So there is no risk of explosion with Helium. That is why it has replaced hydrogen in dirigibles.

Answer 7

Helium will never explode - it's a noble gas and chemically inert because it valency shell is full. Hydrogen molecules are looking for any excuse to explode by combining with oxygen.

Answer 8

They are both gasses but different elements with completely different chemistry.
