|hydrogen gas h2||1.54||0.5||8548||54|
Like a helium atom, a hydrogen molecule also has two electrons, and its intermolecular forces are small. The electrical charge is spread across two atoms. The ideal gas composed of more than one atom is hydrogen gas. As gas molecules get larger, they behave less like ideal gases.Is hydrogen always written as H2?
An atom need to attain duplet or octet to become stable. They either donate or recieve electrons to form ionic compound or they share electrons to form covalent compound. Two Hydrogen atom shares electron with each other to form one molecule of hydrogen. So hydrogen is written as H2 .Why is hydrogen gas lighter than air?
Yes , hydrogen is lighter than air because air is mixture of gases like oxygen nitrogen carbon dioxide etc which increase its mass . hydrogen is simply single gas which contains only one proton and electron hence it is lighter.hence hydrogen balloon fly over.What is the balanced equation for hydrogen gas?
The balanced equation for the reaction of nitrogen and hydrogen that yields ammonia is N2 +3H2 produces 2NH3. This equation means that it requires one molecule of nitrogen gas to react with three molecules of hydrogen gas to form two molecules of ammonia.
