Hydrogen is extremely flammable, helium is not flammable at all.
Helium is good for balloons because it is lighter than air, which causes the balloon to float. Helium is also non-flammable, making it a safe choice for inflating balloons. Additionally, helium does not react with the materials in the balloon, allowing it to stay inflated for a longer period of time.
The symbol of Helium is He. Helium's atomic number is 2.
The symbol for hydrogen is H, and the symbol for helium is He.
Helium is a colorless gas that is commonly used to fill balloons to make them float. It is lighter than air and non-flammable, making it safe for use in balloons.
AnswerThere are two variants of helium -- helium 3 and helium 4. Helium 4 is not magnetic but helium 3 is. Its magnetism is, however, of different nature than e.g. that of iron. The magnetism of helium 3 is used for medical lung imaging.
No, it is not safe to put helium in tires. Helium is not a suitable replacement for regular air in tires and can lead to unsafe driving conditions.
it is chemically inert. so generally safe.
Yes. I would go with helium if you can get it. Hydrogen can explode.
Helium
because helium is safe, chemically inert and environment friendly
No, helium balloons are not radioactive. Helium is a non-toxic, inert gas often used to fill balloons because it is lightweight and does not react with other chemicals. It is safe for decorations and festivities.
Helium is lighter than air, which allows balloons filled with helium to float. Its low density also makes it safe for use in air-filled spaces.
HELIUM
Helium is not dangerous to humans or the environment in its natural state. However, inhaling helium can be harmful as it displaces oxygen, leading to asphyxiation. Helium is chemically inert and does not react with other substances, making it environmentally safe.

Helium is lighter than air, so balloons filled with helium will float. It is also non-flammable and safe to use. Additionally, helium does not react with other chemicals, making it a popular choice for filling balloons.
When your eye is near helium, it will not be affected in any noticeable way. Helium is a non-toxic, inert gas that is commonly used to fill balloons. It is safe to be in contact with and does not cause any harm to your eyes.
