Question

What is the order of ip2 values of boron and beryllium? Can we check it by using effective nuclear charge concept or is there any other procedure?

Solution

1) Boron and Beryllium

Boron (At.No.5) 1s2 2s2 2p1
Beryllium (At.no.4) 1s2 2s2

Boron has an unfilled orbital and hence can easily lose an electron to attain stability where as in beryllium having the full filled configuration, the energy required would be much higher to remove an electron from 2s.

The nuclear charge actually experienced by an electron is termed as the effective nuclear charge. The effective nuclear charge Z* actually depends on the type of shell and orbital in which electron is actually present. The relative extent to which the various orbitals penetrate the electron clouds of other orbitals is

The phenomenon in which penultimate shell electrons act as screen or shield in between nucleus and valence shell electrons and thereby reducing nuclear charge is known as shielding effect. The penultimate shell electrons repel the valence shell electron to keep them loosely held with the nucleus. It is thus evident that more is the shielding effect, lesser is the effective nuclear charge and lesser is the ionization energy.

Q. Why we discovered pi in maths as we know that it's value is 3.14............. Instead we can have any other value of it like 6 or 91 It would make easy. And why there are too much digit because we only use 3.14

Q. What is meant by effective nuclear charge?

Q. There are so many problems in integration where we can solve it by using many methods. But there are also other problems which can only be solved using a particular method. I get confused when I see the problem as to how I should solve it. Is there any way through which we can make out which method should be used to solve the problem. Or is practice the only way of attaining that mastery???
