Question

The electronic configurations of some elements are given as: 4m
[Ne] 3s2 3p3 b. [Ne] 3s2 3p4 c. [Ne] 3s2 3p5 d. [Ne] 3s2 3p3 3d54s1
Which element will be most metallic?
Which element will have most negative electron gain enthalpy?
Which element belongs to d-block?
Out of a, b and c which will have least ionization enthalpy?​

Answer 1

In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. ... This is also useful for describing the chemical bonds that hold atoms together.
