Attractive metal-metal bonding occurs in a variety of molecules made of metallic atoms such as Iridium (Ir). These molecules can have different spatial arrangements, called isomers. Current ...

Plants often use organic compounds to defend themselves from herbivory, but they also use metallic elements from the soil for this purpose. Aa Aa Aa Plants and herbivores are locked in an ...

This is due to the increased positive charge on the metal ion and the increased number of electrons that are delocalised, resulting in stronger bonding.

He says: “An acid is a compound of an electro-negative radical with hydrogen, which hydrogen it can exchange for a metal or basylous radical, and it is therefore replacable.” Again ...

Rare earth metal compounds play a crucial role in modern industries, with applications spanning from high-tech electronics to green energy solutions. Vietnam, home to the world’s second-largest rare ...
