1. What are the contributions mentioned in the paper "Deciphering the structural evolution and electronic properties of magnesium clusters: an aromatic homonuclear metal mg17 cluster" ?
The structures and electronic properties of low energy neutral and anionic Mgn ( n = 3−20 ) clusters have been studied by utilizing a widely adopted CALYPSO structure searching method coupled with density functional theory calculations.

3. What is the Ef of the ground state magnesium clusters?
Ef of the ground state magnesium clusters can be expressed as:( ) ( ) ( )Mg Mg MgQ Qf p n p nE E E E−= + − , Q = 0, −1 (3)Generally speaking, if the fragmentation energy is negative for a particular fragmentation channel, the initial cluster is unstable and may dissociate spontaneously by releasing the amount of energy Ef.

4. How many atoms are encapsulated in the magnesium framework?
As the number of atoms increases, the authors find that eventually, for n ≥ 16, one of the Mg atoms is fully encapsulated within the magnesium framework.
