What is the atomic mass of neon give your answer to the nearest 10?
The periodic table shows atomic mass of Ne to be 20.180. Rounding this to a whole number you get 20 g/mole.
What is the difference between neon 10 and neon 11?
There are 10 protons, and 10 electrons in un-ionized neon. 90% of the neon atoms contain 10 neutrons. There are a few with 11 neutrons and around 9% with 12. Those with extra neutrons are called isotopes, the nucleii having 10 protons but a few with different numbers of neutrons.
What is gram molecular mass of neon?
Neon molecular weight Molar mass of Ne = 20.1797 g/mol.
How do you calculate atomic weight?
The atomic weight of any atom can be found by multiplying the abundance of an isotope of an element by the atomic mass of the element and then adding the results together. This equation can be used with elements with two or more isotopes: Carbon-12: 0.9889 x 12.0000 = 11.8668.
What is the meaning of NE 20?
Neon-20 meaning (physics) The major stable isotope of neon, 2010Ne, having ten protons and ten neutrons; it amounts to over 90% of the element in nature. noun.
What are 5 common uses for Neon?

What is the average atomic mass for Neon?
Neon has three natural isotopes: 90.48% of Neon is Ne-20 with a mass of roughly 19.992 amu; 9.25% is Ne-22 with a mass of 21.991 amu; and 0.27% is Ne-21 with a mass of 20.993 amu. The average atomic mass of Neon is (19.992)(0.9048) + (21.991)(0.0925) + (20.993)(0.0027) = about 20.180 amu.
