stars* and they don't need helium they make helium from hydrogen using nuclear fusion
omg im 13 and i know this
helium balloon
False. A star is born when hydrogen starts to fuse into helium.
"Gases" is a five-letter word that starts with "g" and relates to steam, air, and helium, all of which are forms of gases.
For about 90% of a star's existence, it fuses hydrogen into helium, producing lots of heat. When the hydrogen starts to become depleted and the helium "ash" starts building up, the star may expand into a red giant, in which it fuses helium into carbon and heavier elements.
The noble gas notation starts for elements after helium. Helium has no noble gas notation. Its electronic configuration is 1s2
Your body does not need helium. Helium is an inert gas, and it is not found as a "building block" of any organic material, or any other materials for that matter.
Helium ions can be synthesized by removing electrons from a helium atom and it would need a tremendous energy.
gaseous state
Helium atoms only need 2 valence electrons to have a filled outermost energy level because helium is in the first period of the periodic table and its outermost energy level can only hold a maximum of 2 electrons.
to lift 1 kg or 2 pounds you need 0.16 kg of helium so for 2000 pounds you need 160 kg of helium or 320 pounds at 1 atmosphere
Yes.
Helium is 4g/mol, so 6.46g of helium is 6.46/4=1.62 moles He.
