How do you find the atomic radius and ionic radius?
Atomic is the distance away from the nucleus. Atomic radius increases going from top to bottom and decreases going across the periodic table. Ionic radius is the distance away from the central atom. Ionic radius increases going from top to bottom and decreases across the periodic table.
Why is the atomic radius of Fe2+ and Fe3+?
Fe2+ is greater in size as it has lost less electrons than Fe3+ . So, the nuclear pull is more strong on Fe3+ decreasing the atomic size. Thus Fe2+ is greater in size.
What is the ionic radius of n3?
The ionic radii (in Å) of N3–, O2– and F– are respectively: 1.36, 1.40 and 1.71.
What is the atomic radius of a silver atom?
The atomic radius of Silver atom is 144pm (covalent radius). It must be noted, atoms lack a well-defined outer boundary. The atomic radius of a chemical element is a measure of the distance out to which the electron cloud extends from the nucleus.
What is the molecular weight of silver ion?
