Complexes are formed through ligand binding (donation of a pair of electrons to the central metal atom), and the shape of the complexes is usually determined by steric factors - or how the ligands ...
The first ionisation energy of an element is the amount of energy required to remove the outermost electron. This increases across the peroid as there is an increase in proton number so higher nuclear cha...
Rate of reaction is determined by the number of successful collisions between the reactants per second. A collision is successful if two particles collide with enough energy to react. This can be affected...
Barium has more electrons shells than calcium, so the nuclear shielding is stronger, and the outmost electrons are further away from the nucleus. This results in a weaker attractive force between the elec...
The smallest marbles will give the highest rise in temperature, than the medium and lastly the largest marbles will give the lovest rise in temperature.
The smaller the beeds the larger the surfac...
