What is the atomic mass of neon give your answer to the nearest 10th?
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 mass of neon 22?
21.99amu
The final 8.85\% of the atoms are Ne-22, which is an isotope of neon with 12 neutrons and a mass of 21.99amu.
What is the atomic mass of neon give your answer to the nearest 10?
20 is the atomic mass of neon since it has 20 nucleons. The sum of protrons and neutrons give atomic mass of an element. The atomic number of Neon Ne is 10 and mass number is 20.1797.
Why is the atomic mass of neon in a fraction?
The atomic masses of most elements are fractional because they exist as a mixture of isotopes of different masses.
What mass of neon should be?
Hence, the atomic mass of Neon is 20.18 amu.
What is the gram formula mass of neon?
20.179

What is the melting and boiling point of neon?
Melting point of Neon is -248°C. Boiling point of Neon is -248.7°C. Note that, these points are associated with the standard atmospheric pressure. In thermodynamics, the term saturation defines a condition in which a mixture of vapor and liquid can exist together at a given temperature and pressure.
What is the mass of one mole of neon?
So, neon has a molar mass of #”20.18 g/mol”#, which means that every mole of neon has a mass of #”20.18 g”#. Now, you know that one mole of any element contains exactly #6.022 * 10^(23)# atoms of that element – this is Avogadro’s number.
What is the number of protons in neon?
Neon has an atomic number of 10. So for an atom to be known as a neon atom, it must have 10 protons. For example, if an atom has 11 protons, it will no longer be neon, but will instead be sodium.
What is the molecular mass of neon?
Neon has a molar mass of 20 grams per mole. It has an atomic number of 10 and on the periodic table it is found in period 2, group 18. It is part of the noble gas group.
