They are helium atoms and have all the properties of helium. Helium is mono-atomic [as are all of the noble gases] Non-noble gases [those gases that react with other elements/compounds] are diatomic meaning that in the gaseous state the atoms are paired on to another.
Kinetic energy best describes the motion of the particles in a piece of steel.
1 mole or 4 g or 0.004 kg of Helium has 6 x 1023 atoms. So, 431 kg of Helium have 65 x 1028 atoms
1 mole of helium (or 4 g or 0.004 kg) has 6 x 1023 atoms. So, 590 kg of helium will have 8.9 x 1028 atoms
2,88 grams of helium have 3,761.1023 atoms; 16,4 grams of zinc have 1,511.1023 atoms.
