why transition elements show metallic character
Answers
Answer:
MARK ME BRAINLIEST IF IT HELPS
Explanation:
Transition elements show metallic character as they have low ionization energies and have several vacant orbitals in their outermost shell. ... This happens because transition metals have unpaired d-electrons. The d-orbital which contains the unpaired electrons may overlap and form covalent bonds.
Answer:
The metallic character of transition elements is because of their low ionization energies and the availability of empty orbitals in their outer shells.
Explanation:
The metallic character of transition elements is because of their low ionization energies and the availability of empty orbitals in their outer shells. This property causes the formation of metallic bonds in transition metals and hence illustrates common metallic properties. These metals are hard, showing the presence of covalent bonds due to the presence of unpaired d-electrons in transition metals. The d-orbital having unpaired electrons can sometimes overlap and build covalent bonds. The greater the number of unpaired electrons present in the transition metals, the larger the number of covalent bonds formed by them. The chromium, tungsten, and molybdenum metals have the highest number of unpaired d-electrons. These transition metals are hence remarkably hard. On the other hand, zinc, cadmium, and mercury are not extremely hard because of the absence of unpaired d-electrons.
