A large difference between the third and fourth ionization energies indicates the presence of:

The element having greatest difference between its first and second ionization energies, is:

A sudden large jump between the values of second and third ionisation energies of an element would be associated with the electronic configuration

Total number of elements which have more ionization energy as compare to their next higher atomic number elements. Li, be, C, N, O, F, Ne

The atomic number of helium is 2 and the atomic number of lithium is 3. Is it possible to have an element with atomic number 2.5?

Where a, b,c, d, e,f,g, h ar 3^(rd) period elements. If difference between atomic number of elements b and e is x and difference between atomic number of elements c and f is y . What is the value of x-y .

No. of different matrices that can be formed with elements 0, 1, 2 or 3 each matrix having 4 elements is

In the disintegration of a radioactive element, alpha - and beta -particles are evolved from the nucleus. ._(0)n^(1) rarr ._(1)H^(1) + ._(-1)e^(0) + Antineutrino + Energy 4 ._(1)H^(1) rarr ._(2)He^(4) + 2 ._(+1)e^(0) + Energy Then, emission of these particles changes the nuclear configuration and results into a daughter nuclide. Emission of an alpha -particles results into a daughter element having atomic number lowered by 2 and mass number by 4, on the other hand, emission of a beta -particle yields an element having atomic number raised by 1. How many alpha - and beta -particle should be emitted from a radioactive nuclide so that an isobar is formed?

Which electronic configuration of an element has abnormally high difference between second and third ionization enthalpies ?
