Since the number of electrons and their arrangement are responsible for the chemical behavior of atoms, the atomic number identifies the various chemical elements. Each electron is influenced by the electric fields produced by the positive nuclear charge and the other (Z – 1) negative electrons in the atom. Therefore, the number of electrons in neutral atom of Neon is 10. The number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus. Neon-22 is composed of 10 protons, 12 neutrons, and 10 electrons. Neon-21 is composed of 10 protons, 11 neutrons, and 10 electrons. Neon-20 is composed of 10 protons, 10 neutrons, and 10 electrons. Mass numbers of typical isotopes of Neon are 20 21 22. Isotopes are nuclides that have the same atomic number and are therefore the same element, but differ in the number of neutrons. The difference between the neutron number and the atomic number is known as the neutron excess: D = N – Z = A – 2Z.įor stable elements, there is usually a variety of stable isotopes. Neutron number plus atomic number equals atomic mass number: N+Z=A. The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10 -19 coulombs. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. Show Electronic configuration of Neon.Neon is a chemical element with atomic number 10 which means there are 10 protons in its nucleus.

no electron is available for bondingĢ) It is mainly use to make switching gears and diving equipmentģ) Neon is important component in cryogenic refrigeratorĥ) It is use in lung diffusion test as a tracker gas Neon show 0 valency Because it’s octate is completeĤ) Atomic radius : Atomic radius of neon is 38 pmĥ) Reactivity : It is non reactive element because it’s outer most shell is full.
