Chlorine has two isotopes 35Cl, with a mass of 35.00 amu and 37Cl, with a mass of 37.00 amu. If 77.5% is mass 35.00, what is the average atomic mass of Cl? What is the atomic weight of a hypothetical element that consists of the following isotopes in the indicated relative abundances...
Neon is abundant on a universal scale; it is the fifth most abundant chemical element in the universe by mass, after hydrogen, helium, oxygen, and carbon (see chemical element).[34] Its relative rarity on Earth, like that of helium, is due to its relative lightness, high vapor pressure ...
The atomic mass for neon is approximately 20.2 amu. What are reasonable estimates of the relative percentages of neon-20 and neon-22, respectively? What is the mass, in amu, of an average lithium atom? Why is the average atomic mass...
and deviate significantly (e.g. by more than 2[sigma]accepted for 20Ne) relative to the accepted values in the 1983 Atomic Mass Evaluation (based on nuclear reaction data), but are in excellent agreement with prior (less precise) magnetic sector-based mass-spectrometric measurements of these ...

Due to its relative inertness, neon does not form any known stable compounds in nature, according to Chemicool. There are several researchers, with articles published in Nature and Foundations of Chemistry, who want to rearrange the Periodic Table to move helium next to hydrogen and promote neon...
the frequency of the received wave appears to have decreased. The change in frequency is proportional to the velocity of the source relative to the receiver. This phenomenon is known as theDoppler effect. The combined signal of two closely spaced frequencies will beat at the beat frequency Δf...
Total collision cross sections for the scattering of metastable 23Sand 21SHe atoms in helium, neon, and argon have been measured using a thermal‐energy atomic beam in which a fraction of the helium atoms are excited by electron bombardment. The excited particles are detected by measuring the se...
