A substance that donates a proton (H+)

The valence electrons of transition metals are found in d-orbitals. When the metal ion forms a complex with ligands the d-orbitals split into two different energy levels, and the gap between these levels ...

These two types of bonding are very similar and so can easily be confused however this question specifically wants the difference between them. Covalent bonding occurs when a pair of nuclei share a pair o...

A reaction will occur if two reactants collide with each other with enough energy to overcome the 'activation energy'. The activation energy is the minimum amount of energy the reactant particles need in ...

In group 2 elements, the reactivity is a measure of how easily the atoms lose outer shell electrons. An atom at the top of the group, such as magnesium, has less shells meaning the atomic radius is smalle...
