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.
No. Helium is lighter than air
Yes, a lead atom is heavier than a helium atom. Lead has an atomic number of 82, while helium has an atomic number of 2. Atomic number represents the number of protons in an atom's nucleus, and since lead has more protons than helium, it is heavier. Additionally, lead has a higher atomic mass (207.2 amu) compared to helium (4.0026 amu), further confirming that lead is indeed heavier than helium.
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.
hydrogen
Helium is heavier than hydrogen. Hydrogen is the lightest and simplest element in the periodic table, while helium is the second lightest element.
Nitrogen is the heavier gas (mass of 28) compared to helium (mass of 4).
Helium is lighter than air
yes.
Helium exists as a monatomic gas, with atomic mass of 4.0. Thus any gas with a molecular mass higher than 4.0 would be heavier than helium. Hydrogen is the only gas that is lighter than helium; all others are heavier than helium.
Yes. air is heavier than helium.
A sulfur atom is about 32 times heavier than a helium atom. This is based on the atomic masses of sulfur (32 amu) and helium (4 amu).
no, steel is heavier
density of copper = 8930 kg/m^3 & density of brass = 8700 kg/m^3 copper is heavier
Heavier but safer. Look what happened to the Hindenburg:(
Tin is heavier then Copper.Copper has an atomic number of 29, while Tin has an atomic number of 50.
Silver is almost twice as heavy as copper.
