20-Ne
Err, Neon, in an isotope mix.
Neon-12
Neon-20 is considered an isotope because it has the same number of protons as the regular isotope of neon (neon-22), but a different number of neutrons. Isotopes are variations of an element that have the same number of protons but different numbers of neutrons.
In order to have an equation, we need to know what isotope of neon we are dealing with. Neon 2 is not an isotope.
10 neutrons in Ne-20 isotope
Neon has 10 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a neon isotope = Mass number - 10
The element with 10 protons is neon (atomic number 10). Since the number of protons is equal to the number of electrons in a neutral atom, neon also has 10 electrons. With 12 neutrons, the isotope of neon described is neon-22.
Na -23 is the most abundant isotope, because the atomic massfor Na on the periodical table of elements is 22.99 and 22.99 isclosest to 23.
Number of neutrons = Atomic mass - Atomic number Atomic number of neon: 10 Atomic mass: depending on the neon isotope, each isotope has a different mass
The most common isotope of Neon has 10 neutrons.
The nucleus of neon contains 10 protons and 10 neutrons for the most stable isotope of neon.
An isotope of Neon. This isotope accounts for between a fifth and a quarter of the element.
