The various species of atoms whose nuclei contain particular numbers of protons and neutrons are callednuclides. The Galileo spacecraft atmospheric entry probe found that even in the upper atmosphere of Jupiter, the abundance of neon is reduced (depleted) by about a factor of 10, to a level of 1 part in 6,000 by mass. In fact their absorption cross-sections are the highest among all stable isotopes. Thechemical symbolfor Hafnium isHf. Thomson eventually concluded that some of the atoms in the neon gas were of higher mass than the rest. A more curious example is hydrogen fluoride, whose density at 25C is $1.15\text{ g/L}$ despite apparently having a molar mass of only $20.006\text{ g/mol}$. 113Cd has specific absorption cross-section. The compounds of neon currently known include ionic molecules, molecules held together by van der Waals forces and clathrates. For example, the neutron number of uranium-238 is 238-92=146. In December 1910 Claude demonstrated modern neon lighting based on a sealed tube of neon. It is commercially extracted by the fractional distillation of liquid air. Since the activity of the sun was very unlikely to have changed during the two-year mission, it seems that a type of space erosion was causing the discrepancy, micrometeoroids or the particles simply removed some of the original neon from the top surface of the lunar rock. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100. Multiply the number of atoms by the atomic weight of each element found in steps 1 and 2 to get the mass of each element in Ne: Molar Mass (g/mol) Ne (Neon) 1 20.1797 = 20.1797.

Lutetium is the last element in the lanthanide series, and it is traditionally counted among the rare earths. The first step to finding the molar mass of Neon is to count the number of each atom present in a single molecule using the chemical formula, Ne: Multiply the number of atoms by the atomic weight of each element found in steps 1 and 2 to get the mass of each element in Ne: Finally, add together the total mass of each element to get the molar mass of Ne: Use uppercase for the first character in the element and lowercase for the second character. Capitalize the first letter in chemical symbol and use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al.
