Everything has problems, He has the compound that is best known for causing vocalsclorosis, the sound defening tone, it is also used to make the date rape drug happinotiness. So to answer your question a problem is a problem.
No, helium can escape through the microscopic pores in copper pipe due to its small molecular size. It is not an effective choice for helium containment. Stainless steel or specialized materials are typically used for helium gas containment.
Helium is not a metal. It is a noble gas located on the far right of the periodic table. Copper, gold, and mercury are metals.
Elements
They are symbols that are in the periodic table. He = Helium Cu = Copper Hg = Mercury
The elements helium, copper, neon and argon are commonly referred to as noble gases. These are mainly obtained from air in an air separation unit.
copper is made up of hydrogen and helium, as well as other material(s) produced in labs, such as boron.
The density of helium is less than the density of air. You can infer this without doing any calculations by thinking about the classic example of inhaling the helium from a balloon and talking. Your voice gets squeeky high because helium is less dense than air - that is, your sound waves propagate faster through helium than through air, therefore helium is less dense.
All living things contain carbon as an essential element for organic molecules. Helium, sodium, and copper are not typically found in high abundance in living organisms.
Through nuclear fusion of hydrogen to form helium
Helium is an element on the periodic table and is one of the basic building blocks of the universe. It is formed through nuclear fusion in stars, releasing helium during the process. On Earth, helium is extracted from natural gas deposits through a process called fractional distillation.
helium molecules are much smaller than the molecules of wood pulp that make up the structure of paper. Thus helium gas will quickly dissipate through the paper itself, and into the environment without producing the necessary "lift".
A helium balloon reduces in size because the helium slowly seeps out through the wall of the balloon.
