This is because in Neon the Van der Waals radius is present and in Fluorine the covalent radius is present.Since, the Neon is noble gas and it contains Van der Waals radius which is larger than covalent radius the atomic radii of Fluorine and Chlorine will be 72pm and 160pm . I do not know.

Neon is the second noble gas.

Hence, flourine is smaller than neon. It is known that the Van der Waal's radius is greater than the covalent radius. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. However if one looks at the Bohr Diagrams of both elements, it can be seen that Lithium has one electron in its outer shell and Neon has eight. It is found in the atmosphere at a concentration of about 0.002% . When a few thousand volts is applied to neon, it emits an orange/red light. But I am confused about C and D. I did try to search online but my questions just increased.

Neon is also used in h... Home | Sell Offers | Buy Offers | Structure Search | Neon Supplier. Neon is a chemical element with atomic number 10 which means there are 10 protons and 10 electrons in the atomic structure. It represents the closing of the n=2 shell of electrons. By size, I will assume volume. Ne will have bigger radius than Na+1 because in Ne there are equal number of electrons and the number of protons. The chemical symbol for Neon is Ne.. Atomic Mass of Neon.

Like krypton, neon was discovered through the study of liquefied air. Atomic Radius gets greater down the periodic table and gets smaller to the right in the periodic table. However the atomic radius of neon is 58 pm (58 x 10-12 m) Neon was discovered by Sir William Ramsay, a Scottish chemist, and Morris M. Travers, an English chemist, shortly after their discovery of the element krypton in 1898. This site offers comprehensive information for each element including: who, when & where; up to 40 properties (chemical & physical); over 3,600 nuclides (isotopes); over 4,400 nuclide decay modes; the element names in 10 different languages; and more. Neon is a very inert element, however, it has been reported to form a compound with fluorine. Atomic Number of Neon. The radius of flourine is measured using covalent radius whereas that of neon is measured using Van der Waal's radius. Hence, option A is the right answer. Neon is a chemical element with the symbol Ne and atomic number 10. From the options we see that only option A validates this fact. For example, the atomic-ionic radius of chlorine (Cl-) is larger than its atomic radius. 20.179 Neon. The atomic radius of a chemical element is the distance from the centre of the nucleus to the outermost shell of the electron. Logic and Solution: It is still questionable if true compounds of neon exist, but evidence is mounting in favor of their existence.

C: The atomic radius of fluorine is less than that of neon; D: The nuclear charge in neon is greater than that in fluorine; I understand why A is incorrect and why B is correct. The radius of flourine is measured using covalent radius whereas that of neon is measured using Van der Waal's radius. 10: Neon - Neon [Ne] Group: 18 Period: 2 Atomic number: 10 Atomic mass: 20.1797 Configuration: [He] 2s 2 2p 6 Atomic radius: 38 pm Covalent radius: 58 pm Electron affinity: 0 eV Ionization energy: 21.5645 eV Electronic term: 1 S 0 Mass fraction in the earth crust: 0.000000003 Mass fraction in the earth space: 0.0013 Electronegativity: 4.4 It is isolated mainly by the distillation of liquid air. Image showing periodicity of valence s-orbital radius for the chemical elements as size-coded balls on a periodic table grid. PERIODIC TRENDS IN RADIUS OF ATOM AND ION IIT JEE - NEET AdiChemistry IIT JEE. A) Ca B) As C) P D) Cs E) Ne

d) None of these . Natural neon is a mixture of three isotopes. It is known that the Van der Waal's radius is greater than the covalent radius.
