How do you find the atomic mass of neon?
Actually Neon would be lested as having an atomic mass of about 20.18 because of a mixute of isotopes. Z= Atomic number the number of protons in the nucleus which defines the element. in this case Z=10 and this means neon but there is also 10 neurons in the nucleus of the major isotope whcich gives it ^20Ne.

Why is the atomic mass of neon in a fraction?
Reason for fractional atomic mass:
The atomic masses of most elements are fractional because they exist as a mixture of isotopes of different masses. Since the atomic mass of isotopes are different, so average atomic mass is calculated for a single element.

What is called atomic mass?
atomic mass, the quantity of matter contained in an atom of an element. It is expressed as a multiple of one-twelfth the mass of the carbon-12 atom, 1.992646547 × 10−23 gram, which is assigned an atomic mass of 12 units. In this scale, 1 atomic mass unit (amu) corresponds to 1.660539040 × 10−24 gram.
What is atomic mass give example?
It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes. Foe example: Atomic mass of Na is 23 u. Sodium has 11 protons and 12 neutrons, hence it is equal to 11 + 12 = 23.
