The increasing order of atomic radius of carbon oxygen fluorine chlorine bromine is
Answers
Explanation:
florine<oxygen <carbon<chlorine <bromine
Answer:
The increasing order of atomic radius is
F < O < C < Cl < Br
Fluorine < Oxygen < Carbon < Chlorine < Bromine
Explanation:
→ As we move from top to bottom in a group atomic radius increases due to increase in size of atom and the number of orbitals.
→ As we move from left to right in a period, atomic radius decreases due to increase in the effective nuclear charge.
More information:
→Atomic radius is defined as the distance from the centre of the nucleus to the outermost valence shell.
→ It is usually measured in picometre (pm). 1 pm = 10⁻¹² m
→ Increase in shielding effect result in the increase of atomic radii and vice versa.
→ Covalent radius is defined as the one half of the internuclear distance between two identical atoms bonded by a single covalent bond.
→ Metallic radius is defined as the one half of the internuclear distance between two metal atoms in a crystalline lattice.
→ Ionic radius is defined as the distance from the centre of the nucleus to the most distant electron cloud bound to it within an ion.
→ Van der walls radius is defined as the one half of the internuclear distance between two adjacent atoms of a substance in the solid state.
