Helium-3 (3 He [1] [2] see also helion) is a light, stable isotope of helium with two protons and one neutron. (In contrast, the most common isotope, helium-4, has two protons and two neutrons.) Helium-3 and protium (ordinary hydrogen) are the only stable nuclides with more protons than neutrons. It was discovered in 1939.
99.8% pure compressed deuterium gas, in lot size of 850 L (142 g). Also sold by same supplier in the form of heavy water at price of 3940 USD per kg deuterium. [12] In 2016, Iran sold 32 tons of heavy water to United States for 1336 USD per kg deuterium. [13] 2: He: Helium: 0.0001785: 0.008 (2.216 × 10 14 kg) 24.0: 0.004 29: 2018: USGS MCS [14]
For gases, departure from 3 R per mole of atoms is generally due to two factors: (1) failure of the higher quantum-energy-spaced vibration modes in gas molecules to be excited at room temperature, and (2) loss of potential energy degree of freedom for small gas molecules, simply because most of their atoms are not bonded maximally in space to ...

Therefore, the amount of mass that can be lifted by helium in air at sea level is: (1.292 - 0.178) kg/m 3 = 1.114 kg/m 3. and the buoyant force for one m 3 of helium in air at sea level is: 1 m 3 × 1.114 kg/m 3 × 9.8 N/kg= 10.9 N. Thus hydrogen's additional buoyancy compared to helium is: 11.8 / 10.9 ≈ 1.08, or approximately 8.0%
