Name: Neon Symbol: Ne Atomic Number: 10 Atomic Mass: 20.1797 amu Melting Point:-248.6 °C (24.549994 K, -415.48 °F) Boiling Point:-246.1 °C (27.049994 K, -410.98 °F) Number of Protons/Electrons: 10 Number of Neutrons: 10 Classification: Noble Gas Crystal Structure: Cubic Density @ 293 K: 0.901 g/cm 3 Color: colorless Atomic Structure. Atomic mass of Neon is 20.1797 u. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10 -24 grams.

Neon Atomic Mass Neutrons

In 1961, the Commission recommended A_r(Ne) = 20.183 based on gas-density measurements. Atthat time, the only reported measurements by mass spectrometry were not calibrated and were not consideredto be reliable enough to serve as the basis for the atomic weight. In 1967, the Commission evaluated theresults of two new calibrated mass spectrometric measurements and recommended A_r(Ne) = 20.179(3). Brick force mac download. In 1985, the Commission reduced the uncertainty of the standard atomic weight further and recommended A_r(Ne) =20.1797(6) by combining the earlier results with new calibrated measurements. The atomic weight and its uncertainty refer to atmospheric Ne.

The annotation 'g' refers to occurrences of Ne with diverse and anomalous isotopic compositions in some minerals and naturalgases, derived in part from earth's mantle and from various nuclear reactions such as ¹⁸O(α,n)²¹Ne and ²⁵Mg(n,α)²²Ne.

A_r(Ne) = 20.1797(6) since 1985
The name derives from the Greek neos for 'new'. It was discovered from its bright orange spectral linesby the Scottish chemist William Ramsay and the English chemist Morris William Travers in 1898 froma liquefied air sample.

Computing molar mass (molar weight)

To calculate molar mass of a chemical compound enter its formula and click 'Compute'. In chemical formula you may use:

Any chemical element. 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.
Functional groups: D, Ph, Me, Et, Bu, AcAc, For, Ts, Tos, Bz, TMS, tBu, Bzl, Bn, Dmg
parantesis () or brackets [].
Common compound names.

Examples of molar mass computations: NaCl, Ca(OH)2, K4[Fe(CN)6], CuSO4*5H2O, water, nitric acid, potassium permanganate, ethanol, fructose.
Molar mass calculator also displays common compound name, Hill formula, elemental composition, mass percent composition, atomic percent compositions and allows to convert from weight to number of moles and vice versa.

Computing molecular weight (molecular mass)

To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets.
Examples of molecular weight computations: C[14]O[16]2, S[34]O[16]2.

Definitions of molecular mass, molecular weight, molar mass and molar weight

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.

Weights of atoms and isotopes are from NIST article.
