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.
Yes it can. helium will not react chemically with copper.
Helium is a non metal.
Elements
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.
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.
copper is made up of hydrogen and helium, as well as other material(s) produced in labs, such as boron.
Sodium
No. You can live without aluminum or helium, but you cannot live without iodine.
Through nuclear fusion of hydrogen to form helium
They are symbols that are in the periodic table. He = Helium Cu = Copper Hg = Mercury
Helium itself is completely non-toxic. It is only dangerous if you breathe pure helium without a supply of oxygen.
A helium balloon reduces in size because the helium slowly seeps out through the wall of the balloon.
