It is these weaker attractive forces … Web9 jul. 2024 · In fact, because of the low number of free electrons, sodium is soft and has a lower melting point than the other two. Metallic Bonding Formation Factors The factors favouring the formation of metallic bonds are: The ionisation energy of the metal should be low so that the valence electrons are loosely held by the nucleus and thus become mobile.

Since Zn, … Web29 mrt. 2024 · Answer. When a substance melts, it releases energy as it’s interatomic bonds break . The stronger the bond, the higher the melting point of the substance. Manganese has a half filled d-orbital configuration with all the electrons spinning in the same direction. This makes it stable and less likely to form bonds with other atoms. merlin group projects in rajarhat
