Among the pair of orbital which orbital will experience more effective nuclear charge ?
4d and 4f

Among the pairs of orbital which orbital will experience more effective nuclear charge ? 3d and 3p

Among the pairs of orbital which orbital will experience more effective nuclear charge ? 2s and 3s

The unpaired electrons in Al and Si are present in 3p orbital. Which electron will experience more effective nuclear charge from the nucleus?

While filling up of electrons in the atomic orbitals, the 4s orbital is filled before the 3d orbital but reverse happens during the ionisation of the atom. Explain why?

What is the value of n and l , if orbital of element is 4d

Assertion : Actinoids form relatively less stable complexes as compared to lanthanoids. Reason : Actinoids can utilise their 5f orbitals along with 6d orbitals in bonding but lanthanoids do not use their 4f orbital for bonding.

Out of MgCl_2 and AlCl_3 , which one is more effective in causing coagulation of negatively charged sol and why?

Describe the orbital picture of C_2H_4 .

Out of BaCl_2 and KCl which one is more effective in causing coagulation of negatively charged colloidal sol. Give reason.

A proton is kept at rest. A positively charged particle is released from rest at a distance d in its field. Consider two experiments, one in which the charged particdle is also a proton and in another, a positron. In the same time t, the work done on the two moving charged particles is
