Different types of atoms have different energy levels. As a result each produces photons with different energy and so the line spectra for different elements will be different. This means that ...

1). The reactants all possess translational, rotational and vibrational energies, and these different energy types may have different efficiencies in transporting the reactants to the transition ...

The Agency assists Member States with practical solutions for their energy planning. It offers different types of energy modelling tools that enable States to make smart energy choices. The IAEA's ...
