Question

what do u mean by block compound? also give it's examples.




plz ansr it urgently it's important yrr plz ​

Answer 1

Elements having electrons (1 to 10) present in the d-orbital of the penultimate energy level and in the outer most ‘s’ orbital (1-2) are d block elements. Although electrons do not fill up ‘d’ orbital in the group 12 metals, their chemistry is similar in many ways to that of the preceding groups, and so considered as d block elements.

These elements typically display metallic qualities such as malleability and ductility, high values of electrical conductivity and thermal conductivity, and good tensile strength. There are four series in the d block corresponding to the filling up of 3d, 4d, 5d or 6d orbitals.

3d- Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn

4d- Y, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Ag, Cd

5d- La, Hf, Ta, W, Re, Os, Ir, Pt, Au, Hg
