Metal hydrides are compounds formed when hydrogen reacts with metals. In these compounds, hydrogen carries a negative charge (-1).
This is the type of bonding seen in metal hydrides, where one atom (the metal) donates electrons to another atom (hydrogen).
Alkali Metals: These are metals that readily form hydrides due to their tendency to lose one electron easily.
This term describes how strongly atoms attract electrons towards themselves; in metal hydrides, hydrogen is more electronegative than the metal.
