The mass number of a conventionally named isotope is the number after the hyphen; in this instance, 20.
Oxidation number
Neon is a noble gas. It is in p block. Atomic number of neon is 10.
The mass number of an element will depend on which isotope of that element is being considered. The element neon has three stable isotopes, and the mass numbers for them are 20, 21 and 22. This means that there will be 20Ne, 21Ne and 22Ne. Remember that all atoms of neon have 10 protons, regardless of which isotope. A link to the Wikipedia article on neon is supplied.
its 2. because its located in the 2nd period.
atomic mass of neon is 20.18
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 atomic number of neon is 10. The atomic weight (not mass) of neon is 20,1797(6).
It is 20.1797.
Neon is a non meta element. Atomic mass of it is 20. Atomic number of it is 10.
Neon. It has the biggest mass number.
The mass number of a conventionally named isotope is the number after the hyphen; in this instance, 20.
Neon
Oxidation number
Neon is a noble gas. It is in p block. Atomic number of neon is 10.
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
Neon is a non meta element. Atomic mass of it is 20 Atomic number of it is1 180.
