which one of the following atoms has the largest radius

Atomic Size and Atomic Radius - The distance from the centre of the nucleus to the outermost shell of an atom is called the atomic radius of that atom (Fig. 2.1..

The distance from the nucleus to the outermost shell depends on the electrostatic attraction (nuclear charge) that the nucleus exerts on the electrons of the outer shell. More the nuclear charge closer are the shell and electrons, hence smaller is the atomic radius of an at..

To Calculate the Radius of Atom by Making Use of Avogadro's Hypothesis - By Avogadro's hypothesis, the actual volume occupied by the atoms in one gram of a substance is 2/3 r d of the volume occupied by 1 gram of the substance. Let us consider a sam..

By Avogadro's hypothesis, the actual volume occupied by the atoms in one gram of a substance is 2/3 r d of the volume occupied by 1 gram of the substance. Let us consider a sample of a substance of mass m and volume V. If M is its molecular weight and Avogadro number i..

A cation is formed by the loss of one or more electrons from the gaseous atom. Thus, the whole of the outer most shell of electrons is removed resulting in the smaller size in the cation. For example, in lithium atom, there is only one electron in the outerm..

Being the first elements of each period, alkali metals have the largest atomic and ionic radii in their respective periods. As we move within a period, the atomic radius and ionic radius tend to decrease due to increase in the effective nuclear cha..

Radius Ratio Rules - For the stability of an ionic compound, each cation should be surrounded by maximum number of anions and vice versa. The number of oppositely charged ions surrounding each ion is called its co-ordination number. The larger is the size of the cation the greater is its ..

The radius of a Hydrogen atom is equal to 1 × 10 -1 angstrom. Write this number in standard form. => 0.01 or 0.001 or 0.0001 or 0.1..

Amiline is a hybrid of the following resonating structures...

Electrons cannot exist at a particular point or in a well-defined orbit (path), according to the above new approach called wave mechanics. This led to the concept of 'most probable regions'. We talk about 'certain regions in space around the nucleus called atomic orbitals, where the prob..
