Question

What do elements in block have in common?​

Answer 1

• the d block element are all metals and most have one ore more chemically active d-orbital electrons.because there is a realatively small differernce in the energy of the different d-orbital electrons ,the number ofelectrons participating in chemical bonding can vary.

Answer 2

The d-block elements are all metals and most have one or more chemically active d-orbital electrons. Because there is a relatively small difference in the energy of the different d-orbital electrons, the number of electrons participating in chemical bonding can vary.
