unknown Helium.....the most uplifting experience a balloon can get.
10000000 helium balloons
Helium is no metal, but a gas (at room temperature at least).
Deep sea divers breath helium and oxygen, helium is also used to inflate party balloons and airship blimps.
The activity is -fusing hydrogen into helium.
Your age, height. ha ha ha whatever perfect answer this only guys.
He - Helium
A balloon filled with helium rises until it reaches a point in the atmosphere where the density of the surrounding air equals the density of the helium inside the balloon. At this point, called buoyant equilibrium, the balloon stops rising because the forces of gravity pulling it down are balanced by the buoyant force pushing it up.
The symbol of Helium is He. Helium's atomic number is 2.
helium in a jar diff from helium atom
The symbol for hydrogen is H, and the symbol for helium is He.
The abbreviation for gas helium is He.
There is no word equation, except that helium will exist as liquid phase in liquid helium
The number of helium balloons needed to lift a person will depend on the person's weight. On average, it takes about 3-5 large helium balloons to lift 1 pound. For example, to lift a 150-pound person, you would need roughly 450-750 balloons. It is important to consider factors like air currents and ceiling height when attempting to lift objects with helium balloons indoors.
